Introduction
The IT Infrastructure Library The IT Infrastructure Library (ITIL) was developed in the late 1980s as a guide for the UK government. It has now become the worldwide standard in Service Management. The framework has proved useful to organizations in all sectors through its adoption by many Service Management companies as the basis for consultancy, education and software tools support. Today, ITIL is known and used worldwide. Public domain framework
From the beginning, ITIL has been publicly available. This means that any organization can use the framework described by the CCTA in its numerous books. Because of this, the IT Infrastructure Library guidance has been used by such a disparate range of organizations, local and central government, energy, public utilities, retail, finance, and manufacturing. Very large organizations, very small organizations and everything in between have implemented ITIL processes. Best practice framework
The IT Infrastructure Library documents best practice guidance. It has proved its value from the very beginning. Initially, CCTA collected information on how various organizations addressed Service Management, analyzed this and filtered those issues that would prove useful to CCTA and to its Customers in UK central government. Other organizations found that the guidance was generally applicable and markets outside of government were very soon created by the service industry. Being a framework, ITIL describes the contours of organizing Service Management. The models show the goals, general activities, inputs and outputs of the various processes, which can be incorporates within IT organizations. ITIL does not cast in stone every action you should do on a day-to-day basis because that is something which will differ from organization to organization. Instead it focuses on best practice that can be utilized in different ways according to need. Thanks to this framework of proven best practices, the IT Infrastructure Library can be used within organizations with existing methods and activities in Service Management. Using ITIL doesn‟t imply a completely new way of thinking and acting. It provides a framework in which to place existing methods and activities in a structured context. By emphasizing the relationships between the processes, any lack of communication and cooperation between various IT functions can be eliminated or minimized. ITIL provides a proven method for planning common processes, roles and activities with appropriate reference to each other and how the communication lines should exist between them. De facto standard
By the mid-1990s, ITIL was recognized as the world de facto standard for Service Management. A major advantage of a generally recognized method is a common language. The books describe a large number of terms that, when used correctly, can help people to understand each other within IT organizations. An important part of IT Infrastructure Library projects is getting people to speak the language. That is why education is the essential basis of an implementation or improvement program. Only when the people involved use a common language can a project be successful.

Quality Approach
In the past, many IT organizations were internally focused and concentrated on technical issues. These days, businesses have high expectations towards the quality of services and these expectations change with time. This means that for IT organizations to live up to these expectations, they need to concentrate on service quality and a more customer oriented approach. Cost issues are now high on the agenda as is the development of a more businesslike attitude to provision of service. ITIL focuses on high quality services with a particular focus on customer relationships. This means that the IT organization should provide whatever is agreed with customers, which implies a strong relationship between the IT organization and their customers and partners. Tactical processes are centered on the relationships between the IT organization and their customers. Service Delivery is partially concerned with setting up agreements and monitoring the targets within these agreements. Meanwhile, on the operational level, the Service Support processes can be viewed as delivering service as laid down in these agreements. On both levels you will find a strong relationship with quality systems such as ISO9000 and a total quality framework such as European Foundation for Quality Management (EFQM). ITIL will support these quality systems by providing defined processes and best practice for the management of IT Services, enabling a fast track towards ISO certification. General benefits of quality management include: Improved quality service provision Cost-justifiable service quality Services that meet business, customer and user demands Integrated centralized processes Everyone knows their role and knows their responsibilities in service provision Learning from previous experience Demonstrable performance indicators. itSMF
The itSMF (IT Service Management Forum) was set up to support and influence the IT Service Management industry. It has through its very large membership been influential in promoting industry best practice and driving updates to ITIL.
Restructuring the IT Infrastructure Library The concept of managing IT services for the improvement of business functions is not new; it predeates ITIL. The idea to bring all of the Service Management best practice together under one roof however was both radical and new. The first series of ITIL amalgamated Service Management from an IT standpoint but could have done more to capture the interest of the business. The business perspective series was published to bridge the gap between business and management and although a success, the series was published at a time when the original ITIL guidance was becoming outdated in some areas. The impact of the new series was therefore limited in the market, but a catalyst in the Service Management industry. ITIL was originally produced in the late 1980s and consisted of ten core books covering the two main areas of Service Support and Service Delivery. These core books were further supported by 30 complimentary books covering a range of issues from Cabling to Business Continuity Management. In this revision, ITIL has been restructured to make it simpler to access the information needed to manage your services. The core books have now been pulled together

The IT Infrastructure Library (ITIL)
There are eight core components (books) of the ITIL Framework. These books combine to form a natural bridge between The Business and The Technology the business uses to achieve its objectives. The core set of material is the following set of tightly coupled areas: Service Delivery Service Support Security Management Business Perspective: The IS View on Delivering Services to the Business (Vol I) Applications Management ICT Infrastructure Management Planning to implement Service Management Software Asset Management.

Why Service Management?
Businesses are now more dependent on IT The complexity of technology has increased Customers are demanding more Environment is becoming more competitive The focus is on controlling the costs of IT To improve customer satisfaction Some IT organizations are losing credibility.
Benefits of Service Management
Improved quality of service – more reliable business support IT Service continuity procedures more focused, more confidence in the ability to follow them when required Clearer view of current IT capability Better information on current services (and possible one where changes would bring most benefits) Greater flexibility for the business through improved understanding of IT support More motivated staff, improved job satisfaction through better understanding of capability and better management of expectations Enhanced customer satisfaction as service providers know and deliver what is expected of them Increased flexibility and adaptability is likely to exist within the services System-led benefits, e.g. improvements in security, accuracy, speed, availability as required for the required level of service Improved cycle time for changes and greater success rate.
The requirement to look at the provision of IT Services in a professional way is driven by a variety of factors. Organizations understand the benefits of having Information Technology (IT) throughout their structure. However, few realize the potential of truly aligning the IT department‟s objectives with the business objectives. Most organizations are beginning to recognize IT as being a crucial delivery mechanism of services to their customers. The starting point for IT Service Management (ITSM) and the ITIL Framework is not the technology, not the processes; it is the organizational objectives.

The Functionally Oriented Organization
Most businesses are arranged hierarchically. They have departments, which are responsible for a group of employees. There are various ways of structuring departments, for example by customer, product, region or discipline. Quick Question In this type of arrangement, we often see that: (Select one of the following) a) Communication is ineffective b) Inter department activities are clearly defined c) Processes are optimized to reduce duplication of effort

The Process Driven Organization
A process is a logically related series of activities for the benefit of a defined objective. This slide illustrates cross-functional process flows. Quick Question Can the concept of processes “linking” functional areas together apply to business departments as equally as it can to IT functional areas? YES/NO
Four key activities or concepts with processes: 1. Inputs 2. Outputs 3. Goals 4. Monitoring

IT Service Management (ITSM) Focus
The Four Perspectives There are four perspectives to explain the concept of ITSM. Organization Perspective Involved with alignment of the vision, strategy, goals of the day-to-day activities in IT. The organizational perspective (the issue ensures that we align the vision, strategy and goals of the business with the delivery of IT services. People Perspective Concerned with the “soft” side: IT staff, customers, & effective management of external suppliers. The people issue is without doubt where we – as IT Service Management professionals face our greatest challenges. Technology Perspective Takes into account hardware & software, budgets, tools. Historically, the technology considerations got most attention. Now we understand that without well-defined processes we can often make inappropriate selections in this area. Process Perspective Relates the end-to-end delivery of service-based on-process flows. More and more people see the importance of processes (the primary purpose of this program is studying some of these in detail).

The Objective Tree If we accept that the objectives are the starting point for the provision of IT Services, how can we position the delivery of services and the utilization of the ITIL Framework? The objective tree is a very powerful tool, not only because it shows the benefit and alignment of IT and Service Management principals, but also in being able to effectively sell the concepts to businesses. See if you can follow along in the following paragraphs and match the sentences to the above objective tree. To meet organizational objectives, the organization has business processes in place. Examples of business processes are sales, admin and financial departments working together in a “sales process” or logistics, customer service and freight who have a “customer returns process”.
Each of the units involved in these business processes needs one or more services (e.g. CRM application, e-mail, word processing, financial tools). Each of these services runs on IT infrastructure. IT Infrastructure includes hardware, software, procedures, policies, documentation, etc. This IT Infrastructure has to be managed. ITIL provides a framework for the management of IT Infrastructure. Proper management of IT Infrastructure will ensure that the services required by the business processes are available, so that the organizational objectives can be met.

Change and Continuous Improvement
The Deming Cycle
This model is the work of Dr Edwards Deming, an American statistician whose theories were a major contributor to the Japanese economic revival in the post-World War 2 period. His ideas regarding design improvement, product quality, testing and sales led to many Japanese successes, including the growth and domination of their automobile industry. “We have learned to live in a world of mistakes and defective products as if they were necessary to life. It is time to adopt a new philosophy...” W. Edwards Deming (1900-1993) The four key stages of the Deming Cycle are plan, do, check and act, after which a consolidation phase prevents the „circle‟ from rolling down the hill, as shown above. This consolidation phase enables the organization to take stock of what has been taking place and to ensure that improvements are properly embedded.

Release & Control Implementation

Where do we want to be?
To impress stakeholders (e.g. customers, investors, personnel) your organization will have to communicate the „vision‟ and why they should do business with you, e.g. because you are the cheapest, the most reliable etc. The vision can be communicated in the form of a mission statement (see slide). The mission statement should be a short, concise description of the objectives of the organization and the values it believes in. A vision statement will address the following: Ensure all have a common understanding of the “direction”. Encourage all to take actions that promote the “direction”. Draw together the actions of many. Act as a summary for senior management As a check to ensure that the vision is suitable, you should be able to answer “yes” to the following: Can I outline the vision within 5 minutes? If asked can I explain to each stakeholder “what is in it for them?”
Next – is there a business case? What risks do we face? What gaps have to be bridged?

The “GQM” paradigm Tools assessment.
The most important question that needs answering is whether the “initiative” or adoption of a CSIP (Continuous Service Improvement Program) will deliver sufficient revenue/savings to justify the expense. The principle challenge is that much of the benefit cannot be quantified (e.g. quality, flexibility, service satisfaction). Concerning Risk Management, we must remember that this initiative is not the only one competing for organizational budget. What is the effect on other initiatives if this IT initiative is successful at attracting funds? In addition, what risks will be faced after the program has begun? The salient point is that risks will always be present, so do not attempt to eliminate them – simply get to understand them. The gap analysis is generally an opportunity to use “scores” to measure current and future expected levels of maturity. For example, a five level model of maturity is defined in the OGC “Planning to Implement Service Management” text (Initial, Repeatable, Defined, Managed, and Optimized). Where are we now?
A „health check‟ based on the current procedures can be used as an objective way of assessing the effectiveness of Service Management Processes in an organization. This assessment should aim to identify those areas running well, determine which best practices are in current use and should be retained, and pinpoint problems or constraints. This can be carried out as „self-assessment‟ as well as commercially available solutions. Health checks also determine the maturity of your organization. This is important if your target is better IT and business alignment. How will we get there?
Starting point determined by maturity Awareness campaign Managing organizational change Cultural change Roles & Responsibilities Education Tools.
The starting point should not be determined on the emotions or “feelings” of an individual. The starting point will be a combination of current maturity levels of the IT organization, the IT processes as well as overall organization priorities, IT “pain points”, process interdependencies (e.g. you cannot have Problem without Incident Management) and other factors (including budget, available resources and current workloads). The most important aspect of the communication plan is that it needs to be ongoing and not just given enthusiastic support at the outset of the CSIP initiative. Under the banner of managing organizational change, it simply is not enough to get a group of people together that have project management and ITIL skills and experience. There is a multitude of issues that have to

be considered and addressed (including resistance, gaining and keeping commitment, involvement and communication). Cultural change is largely reflected in the leadership/management style that is prevalent in the organization. Remember that some organizations suit dominant leadership styles (e.g. Regimented organizations such as military units). Careful role definition is required (see later section on using the ARCI model), especially when considering the allocation of new activities to existing staff (overload) or the conflict that could arise when processes are implemented across traditional hierarchical models. As people are an integral part of the CSIP, there is a need to provide appropriate levels of education: the critical element being timing of delivery. All too often we see education programs delivered only to witness a lack of follow up activity that gives the participant an opportunity to put the theory into practice. Finally, tools. The raging debate is which comes first: tools or processes? In reality, most organizations have a variety of IT Service Management tools already. It is not the place of this program to suggest that existing tools are a wasted investment; however, the commonly accepted principle is that the processes should be supported by the tools and not the other way around. How do we know when we’ve arrived?
Critical Success Factors (CSFs) Key Performance Indicators (KPIs) Organizational drivers o Delivering the business wish list.
We need to use measures and metrics to help us determine a “point of acceptance” with regard to process improvements and progress of the CSIP. CSFs are quite simply the things that we have to be able to do. They tell us in qualitative terms the basic objective for a process (e.g. the CSFs for Change Management can be (a) a repeatable change process, (b) ability to deliver change quickly, (c) deliver organizational benefits via change management). KPIs can be considered the quantitative elements of a process that give us a guide to the process efficiency (e.g. the KPIs for Change Management can be (a) the number of rejected RFCs, (b) the size of the change backlog, (c) quantity of changes delivered according to RFC schedule). Note that there are generally a lot more KPIs than CSFs for a given process. Organizational drivers are the points raised by “business people” as their “wish list” for the IT department. There have been many surveys conducted over many years, but the essence of what business people want from their IT departments can be condensed into several points. These include support business operation, facilitate delivery of electronic services, help to deliver business strategies, enable change to match pace with required business change. How do we keep going?
Deliver quick wins Encourage a sense of “Process? Yes - that is the way it‟s done around here” Ongoing monitoring and reviews

Revisit the “vision” Manage knowledge base.
Elements derived from the OGC – Planning to Implement Service Management Quick wins should be used to help drive more change that is medium to long-term. Also, consider what your legacy of change will be. Consider in 10 years time when all current staff have moved on or been replaced. When asked why certain activities are carried out the way they are – what will be the response? “That is the way it‟s done around here.” Perhaps that could be considered a good legacy, if part of “the way it‟s done around here” involves continual monitoring and reviews. The real essence of a CSIP is the first word of the acronym. Continuous! The way to create continuity is to go back to the start and begin again. Remember it begins with the VISION. The vision must essentially promote business and IT alignment. Knowledge management is another way to ensure the legacy of the work you do is not lost. The rate of change, staff turnover, expectations of performance and market place competition are all heading in an upwards direction. With these trends, the organization cannot afford to retain knowledge and learn from previous mistakes and lessons. The CSIP must include in its overall design elements consideration for the gathering, organizing and accessibility of data/information/knowledge. A follow up point - KPIs
If you don‟t measure it, you can‟t manage it. If you don‟t measure it, you can‟t improve it. If you don‟t measure it, you probably don‟t care. If you can‟t influence it, then don‟t measure it.
The importance of Key Performance Indicators (KPIs) is further enhanced by this quotation from the OGC ITIL Service Delivery Book (Availability Management). While it is specifically mentioned in Availability Management, the message is applicable to all process areas. KPIs for: Release Change Configuration.

Dealing with learning and change
Model from Elizabeth Kubler-Ross
This is a useful concept from Elizabeth Kubler-Ross. Human beings are generally predictable. When faced with change most of us go through a series of emotions as reflected in the above diagram. Perhaps you can even relate this diagram to yourself. Implementing ITIL Service Management is about going through changes. The key point is that these emotions are a natural response and they cannot be bypassed. Awareness and education prepare people for the resistance that everybody will feel. Goal: The goal of Release Management is to conduct management and distribution of software and hardware versions in use, which are required to provide IT services in order to comply with agreed levels of service. Release Management controls the actual “doing” of the change. (The actual rollout, and the associated work leading up to the rollout). Why do we have Release Management? How does it differ from Change Management?

Scope: Planning, designing, building, configuration and testing of hardware and software to create a set of Release components for a live environment. The Release Management process is often thought of as a “doing” process. However, we need to remember that the process is controlling the doing work, not actually doing the work itself. The actual “doing” work is carried out by people with specific and relevant skills. The process activities coordinate the planning, preparation and scheduling of a release to a live environment.

Release Management
Release Management Concepts
Release definition (& identification) Release Policy & Planning Release unit Release Types (full, delta, package) DSL DHS CMDB Build, Test, Back-out plans.
Release - Definition A collection of authorized changes to an IT Service Defined by the RFCs that “it” implements Release - Identification Typically, releases are identified as: Major software releases and hardware upgrades Minor software release and hardware upgrades Emergency software and hardware fixes. Major Release – important roll out of software and / or hardware. This would be a large-scale upgrade to your infrastructure or a critical IT Service. Minor Release – minor patches, fixes, or small improvements resulting from the incident / problem processes. Emergency Fix – Be careful with this one. People tend to use Emergency Fixes and Emergency Changes as an excuse to fast track releases. All environments need to be careful about this.

Release – Policy & Planning Contents of the Policy Release numbering and naming conventions Definition of major and minor releases Direction on the frequency of major and minor Releases ID of business critical times to avoid for implementations Expected deliverables for each type of Release Guidance as to how and where Releases should be documented The policy on the production and degree of testing of back-out plans The agreed role A description of the control process. The policy establishes the rules for the process. The policy is typically presented as a document that will define the (unique) numbering of releases, as well as the allowable frequency and times that are permitted by the business. There may be one document per organization, or an umbrella set of guidelines for each supported system or IT service. Finally, the level to which releases need to be managed will be defined in the Release Policy. For example, it may be decided that controlled releases are not required for printers.

The portion of the IT Infrastructure that is normally released together.
The key word in this ITIL definition is “normally”. ITIL always allows room for exceptions. In the diagram, we can see that the release unit could be defined at a Module, Program, Suite or System level. If we decide on a system level release unit, we need to understand the impact on all the individual components. The important point to remember here is that you can select different release units for different elements of the infrastructure. The decision on release units will be dependent on a variety of factors. Considerations relating to resource requirements, complexity of interfaces, ease of implementation, availability of test environments, etc. will all have an impact on the decision.

Release Types
Quick Question If deploying a Standard Operating Environment (SOE) containing the operating system and several applications and various patches, is it a delta, full or package release? Answer:
The concept of different release types helps IT Service Management professional ensure that software and hardware is released in “logical bundles” (referred to as “release units”). Delta Release = release of only the changed items (error solution (“quick fix”) Full Release = release of the full program (including the parts that have not been changed) Package Release = bundled release of multiple changes (multiple error solutions, new/added functionalities)

Definitive Software Library (DSL) A secure compound where definitive authorized versions of all software CIs are stored and protected. “Secure” allows us to see that the software needs to be protected. The compound can be a physical and electronic storage area. “Definitive” means ultimate, perfect, best. By this, we can see that the DSL must hold the „good‟ version of any software that is installed. “All software” reminds us that as service management professionals we are interested in all the software that is used to deliver the services that we provide. The Definitive Software Library is a physical repository for your authorized versions of Software. It stores all physical copies of your software, past and present. It can also hold software that has not been released, including: storage of software items installation scripts images firmware manuals block diagrams development specifications
Quick Question If the DSL holds the “actual” software, where do we store information about the software? Answer:
Managing the DSL
It contains: Agreed versions of software including source codes, objects, executables, etc. including the related documentation. Authorized master software, without unauthorized additions o Licenses are paid Physical storage of up-to-date and undamaged storage media o Disk, tape, CD… Approval by Change Management o Registration in CMDB It is fully separated from the development, testing and production environment. What are the challenges involved in the DSL? How do I manage more than one DSL? What is the relationship to Change Management and Configuration Management?

The DHS is a secure physical storage area for spare infrastructure hardware. Items in the DHS should be referenced in the Configuration Management Database (CMDB). Quick Question If the DHS holds “actual” hardware, which process can utilize the actual equipment held there? Answer:
Managing the DHS
It contains: physical storage of agreed hardware o stock spare parts including the related documentation o stock basic configurations including the related documentation authorized master hardware, without unauthorized additions o maintenance fees are paid fully separated from the development, testing and production environment approval by Change Management o registration in CMDB What are the challenges involved in the DHS? How do I manage more than one DHS? What is the relationship to Change Management and Configuration Management?
Configuration Management Database
Updates to the CMDB will match updates to the DSL & DHS Information about o Definitions of a release & links to originating RFC o CIs that will be affected by a release o Information about targets for a release.
(CI = Configuration Item) We store “information” in the CMDB. Therefore, it is clear that as we make changes to the DSL and DHS we need to make changes to the CMDB. The CMDB must be able to be interrogated to learn what RFC is driving the release activity, what will actually be released, what CIs will be indirectly affected by the release and what actual CIs will be replaced/modified/updated, etc.

Release – Build, test and back-out plans
Build o reproducible, often automated Test o functional, operational, performance integration, Back-out plans o complete reversal o contingency.
When building a release we want to do it in such a way that will provide consistent results. In a software sense, we often rely on tools to “package” up a set of software components into a single executable file that can then be distributed. When considering the testing of releases (both hardware and software) we need to consider a variety of areas – importantly the functional testing must come from those that understand and utilize the functions of a service (typically these are end-users). Back-out plans can be provided in two primary methods. The complete reversal is a strategy of returning to our “pre-release” state, whereas a contingency back-out reflects the reality that often a complete back-out is not practical, so we need to have an alternative path to follow.
Release Management benefits
Quality of hardware & software in the correct version(s) under supervision of Change Management Minimal chance of errors in combinations of hardware and software (stable environments) Virus free and bona fide software Detection of wrong versions and/or unauthorized copies Fewer releases Management of distribution: less risk of incidents
This list represents a summary of the many advantages of a well-implemented and managed Release Management process. The OGC Service Support text lists many benefits, but overall the process allows organizations to deal with the increasing requirement for more releases without compromising the quality of existing service provision. It is important to note that the benefits cannot be delivered in isolation. Benefits can only be derived when all the Release & Control processes are working.

Planning Release Policy
One per organization (or umbrella set of guidelines) Provide guidance on planning releases Release naming, conventions, frequency Business critical periods to avoid Expected release deliverables Expected standards (documentation, etc) Producing back out plans Managing the DSL & DHS Urgent changes and releases.
Ideally, an organization would have just one Release Policy and this may be accompanied by a series of underpinning guidelines. Like most policies, this should be developed in consultation with other ITSM process managers and stakeholders to avoid duplication and generate buy-in. The policy establishes the rules for the process. Release and rollout planning procedures
Plan procedures, guidance & templates Inputs: o Current organizational standards o SLAs and OLAs o Platform specific release building procedures o Training requirements o Licensing and support agreements o Disposal procedures o Security policies and guidelines.
The creation of procedures is often treated as an “un-required task”. However, while all existing staff may have a sound understanding of how certain activities are carried out, we need procedures to help formalize and develop a common understanding. Quite often when a procedure is written two people working together on the same tasks, will disagree over the procedure itself. If such a situation occurs then new staff can often be confused when starting. Having an agreed upon procedure will help to eliminate ambiguity and provide a consistent approach for all staff. Procedures, templates & guidance should be planned to enable the central release management staff to take products from application groups and projects and then to release the software and hardware effectively and efficiently. There are a series of inputs, procedures and documents that are required to plan the Release and rollout procedures.

Release and distribution procedures
Hardware Software o Moving from test to live environments o Archiving previous live versions o Backup live data o Consider geographical spread of sites o Minimize number of dependent steps and staff.
Release procedures should be made as simple as possible and involve the least number of staff possible. Rollback procedures should also be simple, which will reduce downtime should rollback be required. Release and distribution procedures
Updating the CMDB Rollback plan testing Release verification Communication plans & protocols.
Roles and responsibilities
Change manager Release Manager Test Manager Other „functional‟ managers (not part of the process).
Staffing
Critical for access to live environment Enough trained staff to cover absences Sound technical background Awareness of Change and Configuration Management Knowledge of business (to set priorities).
Because Release Management is on the critical path between application development and live operations, and is involved in all-important Changes to live systems, there should be enough trained staff to cater for all aspects of the process AND to cover for absences. Release Managers require a solid technical background, with a good understanding (or an ability to get it) of the IT infrastructure and the services it provides. A good working knowledge of support tools and utilities, and a good grasp of the ITSM principles and practices are essential. A good knowledge of the business assists in (helping to) set priorities.

Training
Technical o Software maintenance and development o Support tools and utilities Process o Change, Configuration, Release o Release Policy, procedures, tools Organizational o Business Issues End-users Release staff.
Typically, the technical training requirements are met well. However, there is a variety of training requirements that cover staff from both IT and non-IT. Remember that one of the primary benefits from training is an “appreciation” of how others will be affected by actions you take. So this is why discussing organizational issues becomes a critical component of the overall training program.
Implementation Software Release and distribution
Build DSL & build environment(s) Migrate current live software into the DSL and inform Configuration Management (CMDB) Test management & software distribution Allow remediation time.
Once the DSL and build environments are available, ensure the necessary security permissions are in place. Application Development staff should be told when to start delivering Release material for inclusion in the DSL and arrangements should be made for all bought-in software to be delivered to Release Management for lodging in the DSL and passed to Configuration Management for recording in the CMDB. Although the procedures should be thoroughly tested before being brought into live use, time should be allowed to resolve any teething problems in the early stages of live use.
To ensure proper adoption, the Release Manager should: o Champion new processes o Monitor uptake and performance o Report exceptions to policy o Automate Release procedures o Ensure staff are thoroughly trained.

Documentation
Initial Business Justification Release Management Implementation Plan Release Policy Release Procedures Handbook o DHS and DSL Library Documents o Release Review Results Release Business Management Reports.
Throughout the planning, design, implementation and review of the Release Management Process, a series of different documentation will be generated. During the planning, design and implementation stages, an initial business case and implementation plan would be delivered as part of any project management framework (e.g. PRINCE2). Once established, the organization‟s Release Management Policy and Procedures Handbook would be employed to ensure that the day-to-day operational activities of release management meet the agreed objectives. Release Business Management Reports provide the organization with the ability to assess the effectiveness and efficiency of the release management process against its agreed objectives. This provides an opportunity not only to identify and address issues, but also to highlight its positive contribution to maintaining a stable production environment.

Activities of the Release Management Process
Release planning
Define the “who, how and when” Back-out plans Plan acceptance requirements Supplier quotes, negotiations Site surveys.
Release planning includes activities that define what will be required to design, build, test and implement a new release. This includes any initial investigation work. The planning for a release requires inputs. The process relies on information provided by the release policy, authorized RFCs, as well as business requirements and any other constraints and dependencies when planning the release.

Back-out planning
Certainly if multiple RFCs are involved (Package Release) the various back-out plans need to be aligned. Are the back-out plans ready if a release cannot be turned back? Testing of the back-out plan(s).
This topic is typically overlooked or only given scant attention. How many times can you recall a situation where the installation work of a release did not go according to the plan? What typically happens? The staff involved say, “We just need a few more minutes!” Quick Question Even if a good back out plan was created what is the primary reason it is not used when the criteria for using it are met? Answer:
The production of back-out plans for each Change is the responsibility of Change Management, but Release Management has a role in ensuring that the back-out plans for each Change within a Release operate together to create a back-out plan. Design, build, configure / assemble
Standard procedures In house or “bought-in” software Automated installation routines (accuracy) Configuration management control o Build results stored in the CMDB to allow reuse Specific test plans for rollout.
The release assembly instructions will need to consider the IT platforms involved. One release may be the combination of many small, multiple platform-specific releases. Each platformspecific release will require unit assembly and then system assembly. Instructions for building platform-specific releases should be detailed in the Release Procedures Handbook. The release assembly instructions should be included part of the release definition. Any automated installation scripts should have associated rollback routines developed. Manual installation processes should be developed in case the automated processes fail. Make use of the CMDB to ensure that required version and number of CIs for a release are available. Steps on managing any discrepancies should be detailed in the Release Procedures Handbook. Rollback plans should be developed and later tested. Assumptions should also be documented for each rollback plan.

Release acceptance and testing
Test the release beforehand o in a (repeatable) controlled test environment o functional testing by users o operational testing by IT service provision Also test the back-out procedures! When a release is rejected back to Change Management!
Develop written steps on using the organization's test environments for release testing. If a test environment for a specific platform is not available, steps on escalating and managing this issue should be documented. The release acceptance test plan should be based on the release acceptance criteria. Similar to modern IT application development testing, the release should be tested independently to ensure it meets the acceptance criteria. Defects may arise in the release testing and documented processes on how to manage these should be outlined in the release procedures handbook. What evidence have you seen of actual user acceptance testing (UAT)? How was it performed (random, structured and controlled)? Quick Question Which group of IT staff are often overlooked but could provide excellent insight with regard to testing? Answer:
Roll-out planning
Producing an exact, detailed timetable of events, as well as who will do what i.e. a resource plan. Listing the CIs to install and decommission. Documenting an action plan specific to the site. Producing Release notes and communications to end-users. Planning communication. Developing purchase plans Scheduling meetings for managing staff and parties involved in the Release.
Remember that there is NOT a flow of activities. It is why in this activity step we see the planning of and the actual purchase of hardware and software (and subsequent storage of information in the CMDB). Remember that we have already covered the design, build, configure activity. Naturally, items will be purchased prior to, during and after this actual work. Essentially, release planning involves the prioritizing and scheduling of approved releases into production. While there are no hard and fast rules on the prioritization criteria, if one is set for an organization then it should be outlined in the Release Procedures Handbook.

ITIL® V2 Practitioner: Release and Control (IPRC) Complete Certification Kit – Second Edition
Once the release schedule is finalized, the details for publishing this updated schedule should also be in the handbook. If particular staff or roles need to notified of such changes in the release schedule, their details should be included in the Release Procedures Handbook. All affected CIs (those introduced, modified and/or removed) should have their details updated in the CMDB. The agreed process for managing urgent releases and any potential negative impact on the production environment should be detailed.
Roll out sequence
This image (from the OGC Service Support text) helps us to understand the approaches available with regard to the roll out of releases. The first point to note is that the Release policy sets the rules for the actual roll out approach adopted. In the first block we can see an initial launch followed by two additional units (consider each of the units to be a workstation, or server, or other piece of infrastructure). In the second release, we see a “big bang” approach and then a phased rollout in the third release. Big bang is generally considered high risk (due to the high impact of failure). Phased rollouts are only possible where release units of differing versions can co-exist. Communication, preparation, training

Most of us face an endless barrage of reports and information on a daily basis. The challenge when designing the reporting structure for any process is not what should be provided; it is what will be done with it? We have almost limitless aspects that we can report on. Therefore, the question is not what reports to provide, but what benefit the report will provide. As a process designer, you will also want to consider how to report on actual improvements that should be made to the process itself on an on-going basis (continuous improvement philosophy). Process relationships
Configuration Management Change Management Software from Developers and suppliers Problem Management and the Service Desk Project Management and for example, PRINCE 2.
Guidance for success
Configuration Management Change Management Release Management Application Design Positioning of software.
Configuration Management – automated software/hardware auditing, data collection, integrity of files (checksums), good status accounting to reduce fees for un-required/unused software/hardware, control policies to prevent unauthorized installations, reduction/consolidation in officially supported variations of the organizational standard. Change Management – limit ability of users to make changes to their own systems, meetings and control points with relevant stakeholders to discuss proposed changes. Release Management – establishing a good (life like) test environment, automation of distribution and installation, disciplined testing by real end-users Application Design – centrally held or distributed data, centrally run or local run of applications, applications covering different countries (languages), and time zones. Positioning of software – thin client model, falling cost of hardware may offset the benefits from centrally run, no/controlled local data storage.

Change Management
Release and Control processes Let‟s now have a look at some of the concepts, terms and language of the Release, Change and Configuration Management process. A robust Change Management process ensures that the Change Manager is in full control of the changes to the IT infrastructure. Change Management is NOT about performing changes risk free. It is about performing changes with a minimal risk OR consciously taken risk. It is therefore important to involve the clients or client representatives in the change management process. The basic essence of Change Management is control & co-ordination and managerial; rather than technical (to contrast Incident Management has a strong emphasis on the mechanical nature of service restoration). Goal: To ensure that standardized methods and procedures are used for efficient and prompt handling of all changes, in order to minimize the impact of any related incidents upon services , and consequently to improve the day-to day operations of the organization. Or to put it another way… Any element of the infrastructure that you “care” about; you want to ensure that changes to that element is done according to a predefined set of activities and checks that will minimize the likelihood of a detrimental change to that element. Quick Question Change Management is more of a: (a) Doing process (b) Coordination process (c) Strategic process
Scope: The Change Management process should account for changes to all elements of the infrastructure that you (as an IT Service professional) are interested in. This will (or should) include: Hardware Communications equipment and software System software „Live‟ applications software All documentation and procedures associated with the running, support and maintenance of live systems. A change is a process of moving from defined state to another.

Is this too broad a definition? Consider using Change Management procedures to make changes to passwords of mission critical systems. How often do the passwords change? Every day, every week, every month? The reality is that if you want to, you will use Change Management to track the changes. A change does not necessarily mean that we have to call a meeting to approve it. We can define standard changes and appoint relevant parties to carry out the change, provided a pre-defined work procedure is followed.

Although some of these elements may have been discussed and covered at the Foundation level, in this program we look in greater detail at the “building blocks” of the process. The process needs to have “high visibility”. Request for Change (RFC)
Triggers Scope Contents Life cycle Post Implementation Review (PIR)
The Request for Change (RFC) is the most commonly understood concept within the Change Management process. It is typically the focal point of discussion when a specific change is being discussed. An RFC can be triggered by a variety of reasons. “Trigger” examples include: Required solution of an Incident or Problem report User or customer dissatisfaction expressed via CRM or SLM The proposed introduction or removal of a new CI A proposed upgrade to some component of the infrastructure Changed business requirements or direction New or changed legislation Location change Product or service changes from vendors or contractors. The PIR/Change Review is designed as a final check that the intended outcome for the change was actually delivered.

Change Advisory Board
A group of people who can give advice to Change Management on the implementation of Change. Representatives CAB/EC Assessment criteria. Most organizations tend to have the same staff attend each change meeting. According to the best practice definition of ITIL the CAB would actually be flexible and dependant on the changes being assessed. When time pressures do not allow a full meeting of the CAB, it will be necessary to identify a smaller organization with authority to make emergency decisions. Such a body is known as the CAB Emergency Committee (CAB/EC). Whether changes are “standard” or “emergency” to improve the efficiency of the process it is necessary to establish a set of (predefined) measures. Having these measures in place brings the added benefit that many changes can be managed through automated systems. Change Models
Standard to Complex Forward Schedule of Changes (FSC) o A schedule that contains details of all Changes approved for implementation and their proposed implementation dates. Projected Service Availability (PSA) o A document that contains details of Changes to agreed SLAs and service availability.
There is a growing awareness that defining change models can save time, effort, resources (and by association money). Models are typically defined for “smaller” changes. However, using the Capacity Management process (modeling) will also permit building of more complex change models. Forward Schedule of Change (FSC) – Changes that have been approved and their date/time of implementation Projected Service Availability (PSA) – agreed details regarding changes to SLAs and service availability Both FSC and PSA require customer involvement – SLM, Service Desk, and Availability Management.

Outsourcing
Questions to ask a supplier regarding Change Management Who is responsible? What controls do we retain? How are business impacts considered? Who sits on the CAB? How is security dealt with? How are changes costed? Outsourcing organizations have a right to make profits. The way they do this is typically by employing “economies of scale”. Such economies of scale come from sharing infrastructure and even sharing services among a number of clients. While we can respect this right, we do need to ask a series of questions of the outsourcing organization. These questions are designed to protect the business and ensure that the outsourcer is aware that their actions can have major impacts. Benefits
IT to business alignment Fewer adverse impact changes Fewer back outs Greater cost controls Increase productivity for end users and IT personnel through stable IT services Large number of changes can be handled without making the IT environment unstable.
Costs
Staff costs include those people involved with the Change Advisory Board, change builders and those staff involved with release and configuration management activities. We should expect that such costs at the outset of working with a new process would be higher. Support tools will quite often be an integrated system that supports a variety of processes (e.g. Change, Configuration, Incident/Service Desk and Problem Management).

Points of attention
Cultural challenges o a single process that is used for all elements of the infrastructure Bypassing „Missing link‟ with other processes Commitment the supplier(s) to the process Volume of changes.
Understanding the possible problems ahead of time allows us to be prepared for and (preferably) avoid them altogether. With regard to Change Management, the list above indicates the typical issues that can be faced. Bypassing is perhaps the greatest challenge and it can be created by pressure from customers OR self created by IT staff that do not see the need to use the process for what they consider to be an insignificant change. Steps to help prevent unauthorized changes will include: Audits Control over configuration items Limiting user access Education and awareness.

Logging and filtering
Logging Complete / Check information Advise o Use an integrated Service Management tool o All members of the organization should be authorized to request Changes (stay innovative!) Filtering Which RFCs are totally impractical? If rejected o Return to applicant with reasons o Applicant has the right to appeal. The IT department has traditionally placed heavy controls on this one area. By only allowing a limited number of people to raise RFCs there is a danger that innovative ideas and suggestions could be missed. However, there is a danger that the change process becomes over burdened if there aren‟t some filter points that will prevent change proposals that have not been properly thought through to proceed.

Classification
Allocation of priorities May already have been assigned by Problem Management (?), but…. Determines the order of changes. Change categorization Establishes the resources required Based on the impact. Ideally, the priority will be agreed upon with the initiator of the change – not left to the initiator. Without a “check” on the priority, we may see a cost justification imbalance (e.g., when Problem Management sees an issue as critical, but the CAB/Change Manager, with other external information, determines the issue is medium priority only). The category of a change helps us understand the level of resources required to actually implement that change. Be careful not to create too many categories, as confusion can cause the value of reporting to diminish. You can create a multitude of categories that may essentially all say the same thing. For example: Facilities Management Move Add Change Software Upgrade Software Installation. In such situations, some staff would use the MAC for a Software Installation, while others will select Software Installation.

Assessment
Assessment of: Effect on the infrastructure and service delivery Capacity and performance Contingency plans Security Effect on other services What if change is not implemented? Current FSC and PSA Costs Extra resources required post change. The CAB, CAB/EC or others nominated by the Change Manager, will carry out actual assessment. Some questions that may help in the assessment of a change: What are the benefits (to the business) of this change? What are the costs of making this change? Is there a sound plan to implement the change? Is this technically the best way? What are the risks associated with this change (both of doing the change and of not doing the change)? Are these risks under control? Are the benefits, costs and risks in balance? How often should the CAB meet? It is important to note that the CAB may not actually meet very often - perhaps a physical meeting every six months. However, the members of the CAB can use electronic tools to review, sign-off, etc. The CAB meetings are also a place to make decisions, not to learn, so meeting agenda and other relevant papers should be sent to participants ahead of the actual meeting.

The CAB is an advisory body. If an agreement cannot be reached, the final decision will rest with the Director of IT, Change Manager, Service Manager or whoever is named as the authorized signatory for change (defined in Change Procedures and/or SLAs). The size and risk associated with a change will often determine who can actually make the approval.

Coordination
While IT staff may desire a single change policy, in reality, it is simply not a practical option (for most organizations). Apart from the negative image that users and customers would form of the IT department under such conditions, there is the added factor that there can be no economies of scale for multiple, single changes. The scheduling of changes will also need to factor in changes that will be required to dependant items (e.g. changing hardware may require an operating system upgrade). We also need to consider the number of changes that can occur at the same time (e.g., a rollout of multiple desktops can be treated as a single change (and the single change will be delivered as a “package release”). To balance these factors we must also consider ways to limit the risks involved should the change not go according to plan. In such a case, we want the single change to be of such a size that we can back out within an amount of time that will allow reversion to the pre-change situation that suits business needs. Forward schedule of changes Based on known plans Short, medium, long (?) Distribution.

Build, Test and Implementation
Development and building Also the back-out procedures! Testing Also the back-out procedures! Preferably in a separate test environment Points of attention for all Service Management processes Use modeling techniques. Implementing Are the end-users familiar with the implementation? Is the Service Desk familiar with the implementation? Do the back-out procedures work? At times that the impact on the IT service provision will be minimal. Once approved the change will be sent to the relevant groups. It is at this point that the actual work of creating the change will begin. The activities associated with Application Development, modifications to standard operating environments, etc. are outside the scope of the Change Management process. However, we can break the activities down into the three major points. Building must ensure that the same methods for building are used in order to maintain consistency. It is also at this stage that the back out plans are developed. Testing is a critical component and should be completed across a number of aspects (performance, security, etc.) It is also appropriate to have separate test environments that are as closely reflective of the production environment as possible. Implementation will take place at a time where any potential disruption to the business will be minimized (traditionally this is outside of work hours, but perhaps there is the opportunity to think laterally and conduct implementation during predefined times of the working day (provided these are known and accepted by business representatives and documented in SLAs).

Evaluation
Was the planning correctly carried out? Was the impact correctly estimated? Was the usage of resources correctly estimated? Was the right result for the change realized? Are the users satisfied with the result? Number incidents on the change Were / are there unexpected side effects? Have detected anomalies been communicated to the CAB for future changes?
The evaluation or change review is our opportunity to learn some lessons that could help to improve future changes and/or avoid mistakes made. The review can be based on a series of questions. It need not be a long exercise. It is important that there is some form of follow up action to ensure that the lessons learned are not lost over time. It may be that the follow up includes a redesign of the actual Change Management process or a modification to the approval matrix. Interestingly, such changes should themselves be done under the control of Change Management.

Roles and responsibilities
Change Manager o Co-ordinate the CAB o Authorize o Report o Measure Change Advisory Board (CAB) o Non-static group o Understand changes o Provide advice CAB/EC (Service desk) o Authorize.
The Change Manager (who can delegate) will carry out a number of change related activities including: Calling and chairing all CAB meetings Issuing relevant paperwork prior to any change related meetings Authorize RFCs (that have met their change approval criteria) Receive, log and prioritize change requests Issue the FSC (via the Service Desk) Look for any negative change related trends Compile and issue change related reports. The CAB will be a dynamic group that includes stakeholders relevant to the changes under review. The Change Manager will chair CAB meetings. The group will review tabled changes (prior to any meeting) and provide advice on any proposed change – regarding authorization or rejection. The CAB/EC primary role is to be available should there be a need to conduct an urgent review. The Service Desk is mentioned, as we should remember that they might have the authority to approve minor changes or changes that meet some pre-defined criteria of measurement.

Planning and Implementation of the Change Management process. Planning
Existing role, new role Decide on Scope Single Change and Configuration Management system Training Metrics, reports, review process.
In most organizations, the Change Management role already exists, or it can easily be assigned to an existing individual. If the process is new to the organization, one of the first tasks that must be completed is to establish the scope of Change Management. Agreeing the scope will be done in conjunction with or will be reflective of the scope for configuration management. Similarly the selection of a tool is further complicated with the knowledge that the same system should be used for Configuration Management. Training in the use of the system should be carried out prior to implementation and contingency must exist to train new staff as they join the IT organization.
Quick Question Why is there such a strong connection between the Change and Configuration Management processes? Answer:
Finally, the measures of performance and the way the Change Management process itself will be assessed and reviewed need to be designed. Implementation

processes are (Release and Configuration). However, other areas would be required in order to deliver a truly effective change management process. The two most notable of these are Problem Management and the Service Desk (function). Problem Management is an important generator of change. Once a known error is discovered in the IT infrastructure, it is necessary to remove that known error. Providing information about upcoming known changes AND receiving information that may generate and RFC AND carrying out pre-defined (minor) changes helps us to understand the importance of communication. The Service Desk is a focal point of communication in the IT Department. Actual procedural examples are provided shortly. We must take into account existing procedures when implementing the process. It will not be practical to run two processes in parallel, so the actual cutover point must be considered. With regard to people issues and Change Management, we need support of management for the process itself and then we need active participation. This is especially true for the IT staff who may attempt to by-pass new practices and procedures as they see them as an unnecessary overhead. Finally, when the process is implemented we may want to consider establishing „change slots‟. These will be times that changes are permitted on a pre-defined, but regular basis. If they can be agreed upon, then it is appropriate to document them in any Service Level Agreements (and OLAs and UCs) that support the affected service/s.

Perhaps it is better to create some form of change ratio. Typically, a large number of changes indicated an unstable infrastructure environment and something that would lead to a high degree of customer/end-user dissatisfaction. However, what if the change were driven by those customers/end-users? If the amount of business change is low, then we should be looking for low levels of change in the IT infrastructure; conversely high change rates in the business can potentially be met with continuous changes in IT to keep pace. Types of reports
Risk Reports Business Impact Reports Bottleneck reports Emergency changes Costs of change General Reports on changes: o Changes per CI o Number of „back-outs‟ o Major change reviews.
Interestingly in the British Standard for IT Service Management (BS15000), which was adopted by Australia, under the banner of AS8018 (and internationally under ISO20000) there is a new defined section for “Service Reporting”. The standard requires that each service report will be clear in its identity, purpose and audience and that the details of the source information provided shall be stated. The purpose for any reports (echoed in the standard) is that they are agreed, timely, reliable and allow for informed decision-making.

Configuration Management
Goal: Configuration management provides a logical model of the infrastructure or a service by identifying, controlling, maintaining and verifying the versions of Configuration items (CIs) in existence. Or to put it another way… Any element of the infrastructure that you “care” about; you want to hold information about that element, so that you can control it. The objective statement indicates that Configuration Management is the verification of components. Scope: Identification, recording and reporting of IT components, including their versions, constituent components and their relationships. The Configuration Management process is often thought of as the most important of all the processes. While the ITIL text will not support such a statement, it soon becomes apparent that Configuration Management provides information to and relies on information from the other ITIL processes. While this could be said of each process for Configuration Management, seeing these connections is a lot easier. Quick Question: What is the principle difference between Asset Management and Configuration Management? Answer:

Configuration Management Concepts Configuration Management Planning
Strategy, Policy, Scope, Objective Key Success Factors (KSFs).
Configuration Identification and CIs
Hardware Software Documentation.
While all process implementations require planning, the concept is highlighted here due to the central role that Configuration Management plays with regard to other best practice processes. During planning the objective and scope must be defined. The Configuration Management plan will also document interfaces to other processes (especially Change and Release Management). There will be an explanation of tools, roles & responsibilities and locations of storage areas (for hardware, software and documentation). The hardware, software and documentation managed by the IT Department are referred to as Configuration Items (CIs). They are identified and labeled as part of the process implementation and on-going management. The relationships between CIs are a critical element of this process and help us to understand the primary difference between Configuration and Asset Management. Identification and registration
Scope: determine width and depth of the CMDB Identify CIs o Determine naming conventions o Record, determine attributes o Define interrelationships o Define the level of detail Hardware and software Network (components) Databases, operating systems, etc.
Configuration Control
Only authorized CIs Change Management relationship.
Configuration Status Accounting
Allows tracking through life cycle. On the various components on a daily basis o Attribute status being developed, purchased, tested, repaired, … o General status

number and sort incidents, problems, known errors, changes, licenses.
Configuration control ensures that we consider how to control the recording of only authorized CIs from their point of arrival to their point of departure. The basic control question is “what will be used to allow updates?”. The most obvious answer to this question comes from the Change Management process and the associated Request for Change (RFC). One element of controlling the CIs is knowing where each Configuration Management (CI) is in regard to its life cycle. The value of the concept can be appreciated when we consider the various reports that could be generated that show different CIs and their incidence of status changes.

Configuration Baseline
Snap shot Link to Change Management and Problem Management.
One of the more “visible” concepts for Configuration Management is the verification and audit activity. This concept is a basic but crucial requirement that is often used as an indicator of the overall process effectiveness. The more errors found when checking “actual” against “expected” is a clear indication of how well the process is performing, in conjunction with the closely aligned Change Management process. This step is also a key element in the management of updates into the live environment (strong link to Release Management in this regard). The Baseline for configuration is a “snap-shot” that allows for future comparison. It is a key requirement when we are considering rollbacks after a change and/or in depth problem analysis. Configuration Verification and Audit
Check actual presence against recorded details in the data store Vital step in checking release contents prior to implementation in the live environment Daily check o Build a procedural check The Service Desk o Logging an incident Audit (by an internal party) o Partial or extensive? Audit (by an external party) o Review of the process o Actual verification.
New employees joining the organization can be educated to complete a daily procedural check on their local infrastructure. Service Desk personnel can conduct mini audits, by asking callers about their location and equipment numbers, etc. However, there is still a place for the more formal methods (especially required for non-visible items like routers, servers, etc.). The external audits can be both a check that the process defined by the organization is being followed; as well as an actual check of CMDB information against actual infrastructure.

Configuration Management Database (CMDB)
Exist to some degree Technology required to support complexity Auto-discovery Personnel details, supplier details Legal benefits
Software and Document Libraries
Collection of software and documents of known status Controlling mechanism for software release.
The Configuration Management Database (CMDB) is the data store for CI information. Most organizations already have a series of spreadsheets and small databases on infrastructure within the IT department. In larger organizations, the growing size and complexity of the infrastructure has forced the use of technology to manage all the associated information. The CMDB can hold a variety of information including details on users, customers, user groups, business units (Caution: consider privacy legislation at this point). The CMDB is also demonstrable and as an auditable concept, it can be used as a compliance mechanism for legal requirements. CI information relating to incidents, problems, known errors, changes, releases; as well as inter CI relationships will be stored in the database. Definitive Software Library (DSL)
Master copy – software Logical area.
License Management
Fines, even imprisonment Internet downloads may require disciplinary measures.
The definitive software library (DSL) is the LOGICAL storage location for master copies of software. The word “definitive” means „ultimate‟, „perfect‟, „best‟. Regarding license management, business people now face harsh financial penalties if they are found to be unable to control and monitor their software usage/licenses. Configuration Management is a crucial process in assisting in the control of software licenses.

ITIL® V2 Practitioner: Release and Control (IPRC) Certification Kit – Second Edition
Configuration Management Database Without knowing it there are already many organizations engaged in Configuration Management practices. Most already have some form of crude Configuration Management Database (CMDB). These CMDBs are often spreadsheets, local databases or even paper records regarding IT asset location, owner, cost, etc. However, the growth in size and complexity of IT environments has dictated the need to adopt sophisticated support tools (including a Configuration Management Database (CMDB). Configuration Management Data Base = a repository of data regarding IT components and their relationships Configuration Item and Variants
A configuration item is a component of your infrastructure that is in place to help deliver a service. This component can be hardware, software, or even documentation (Service Level Agreement). Variants can be used when CIs are similar but not exact. Variants help to keep the total number of CIs down, but they can introduce complexity into the design of the CMDB (and subsequently other process areas that rely on the CMDB information). Configuration Item and attributes
Different CIs require different attributes to be stored. Often the “tool” will determine what attributes can be stored (be cautious of allowing the tool to determine all aspects of the process). Benefits
Management of IT resources Economical, quality services o Less mistakes, therefore less “double costs” Effective and efficient problem solution Effective and efficient processing of changes Optimal support on security issues Helps ensure compliance to legal obligations o Insight in illegal copies, licenses, due dates of contracts Optimal support on issues of budgeting and spending.
Central Data Repository
Having all CI data in one central repository provides all the normal efficiencies of data centralization. The information supports all other ITSM processes such as Release, Change, Incident, Problem, Capacity Management and IT Service Continuity Planning. Providing one database with supporting database views for different purposes provides enhanced reporting at lower costs.

Legal Obligations
Poor management of CIs can have negative legal and financial repercussions on an organization. An accurate CMDB, with good Change Management practices can: Reduce the introduction of unauthorized software/hardware Support more timely and accurate auditing Make software changes more visible and therefore reduce the chances of accidental breaches of licensing agreements. Supports IT Service Continuity Management. In recent times, IT Service Continuity Management has risen to become a higher priority of organizations. Good Configuration Management practices supported by regular offsite backups of the CMDB, DSL & DHS will improve an organization‟s ability to restore operations in a minimal amount of time. Costs
Personnel o Management CMDB, audits, clean up poor data Accommodation o Physical storage of process documents, servers, people Software o In house vs. off the shelf o Tools and equipment for CMDB, audits, reporting… Hardware o Data storage o Collection points and collation servers Education o Tools, procedures, how to audit Procedures o Designing & managing Configuration Management, documentation, instruction sets.
This is an expensive process to implement and maintain! There is no way to disguise the fact that in major organizations the costs associated with tracking and controlling IT infrastructure can be enormous. However, consider the costs of not implementing this process. Computer fraud, software corruptions, viruses, breach of license agreements, etc. The penalties for these events can spell the end to any business. The good news is that while the costs will be relatively high at the start of the implementation, with practice and refined procedures and tools, the operational costs should be able to be kept down.

Points of attention
Wrong level of CI detail (too high or too low) Sticking to manual system Authorization in case of urgent changes outside business hours Over ambitious planning and too high expectations Lack of management commitment Costs-benefit analysis is difficult Time pressure on implementation Overly bureaucratic process/implemented in isolation Tool lacks flexibility.
CMBD Development
The development of an automated CMDB and its associated processes should be treated as per any new system development in an organization. Adequate system specification and design should be undertaken to ensure that what is built meets the desired outputs and outcomes. Adherence to Configuration Management Processes
After implementation, clearly written and supported Configuration Management processes (e.g. using the CMDB) should be developed, communicated and disseminated to ensure that the CMDB maintains its accuracy. A loss of accuracy in the CMDB can have long-term negative implications for the Configuration Management process and your ITIL implementation.

Planning and Implementation Controlling IT infrastructure and services across distributed systems, across multiple locations and support groups requires careful planning. As there are many interdependencies among them, the planning should include Change, Configuration, Release and IT Service Continuity Management. Purpose and scope Consult on purpose, objectives, scope and priorities Standalone vs. consolidated process Purpose statement. The purpose, objectives, scope and priorities for Configuration Management should be carefully considered with other ITSM process managers and IT managers. This will not only ensure accuracy but support buy-in at an early stage. You will also consider whether Configuration Management should operate as a stand-alone function or as a clustered set of inter-linked processes (along with Change and Release Management). A purpose and scope statement should be developed as part of the project plan. For example: To implement one consistent Configuration, Change and Release Management process for
, which will ensure all IT assets are correct and accounted for in all IT environments. The objective might be: To bring all ‟s all IT services and infrastructure components, with their associated documentation, under control, and to provide an information service to facilitate the effective and efficient planning, release and implementation of Changes to the IT services. Objectives Correct and accurate data Documented procedures Standardized naming & labeling Control authorized CIs Audit trails. Priorities based on the organization. For many organizations, some form of phased implementation, including Change Management is essential. The implementation approach may be on an organizational, geographical, customer group, support group basis. Your priorities may be based on the CI relationships (systems, network, desktops), or your implementation approach (e.g. standalone or consolidated with Change & Release Management). A consolidated Configuration, Change & Release Management implementation will take longer and have higher initial costs, but inter-process relationships will be clearer and reduce future maintenance costs from incorporating these processes later.

Manager and team
Considerations Dedicated staff or other roles/projects Joint Configuration, Change and Release team Size of IT infrastructure Change size, frequency and complexity. The typical role titles in the Configuration Management team include Configuration Manager and Configuration Librarian. Current state analysis
Identify and analyze current: Processes Scope and resources Tools (databases/interfaces) Roles and responsibilities Owners of CIs. Most organizations have some form of Configuration Management process already in place. Even if it is a simple spreadsheet, listing traditional IT assets owned. This is in fact true of most of the ITIL processes. There are elements of each process in place – even if it is not referred to as ITIL. In order to move to new & improved state, we must gain a picture of the current Configuration Management situation. This will help identify points of concerns to address, as well as points of strength that need to continue. Plans and design
Structure of the CM plan(s) Steers the design of CM process Affects the CMDB design. Most organizations delegate elements of Configuration Management control to support groups that have expertise in a particular technology or platform. In such cases, the support group manager is responsible for the control of the CIs owned and maintained by the group. Where this responsibility has been delegated, the organization needs to use one central or a consistent set of Configuration Management Plans to ensure consistent practices. A centralized function ensures common practices and procedures. Delegation requires careful management and regular auditing AND all groups need to share a common understanding regarding the process of Change Management as it relates to the management of the CMDB. Regardless of the structure of the Configuration Management Plan, it will play a major role in the design of the Configuration Management process and CMDB.

Planning for implementation
Same as major project activities. Key activities include: Detailed analysis of existing process & staff knowledge Review current data Select CMDB tools Detailed system design Set up CIs. The activities carried out in the detailed planning for implementation are similar to those traditionally carried out in a major system development. More key activities include: Detail procedures Test CMDB and interfaces Finalize roles and responsibilities Promote project Train staff and users. Now we must begin some of the actual work of implementation. Up to this point, we have only identified and analyzed. Most people looking at the ITIL framework are seeking flow charts for all activities. It is relevant at this time to point out that, while a flow chart can provide a good pictorial overview of a process, a lot of the time many activities happen concurrently – and not in a structured flow.

CMBD and DSL set up
Consider Change freeze during set up. Populate and audit CMDB. Test:
Security Backup & restoration CMDB interfaces Contingency plans.
Ideally, during the CMDB setup, the organization could place a freeze on changes while the CMDB is being populated with existing CIs. This will ensure accuracy from day one but depending on the implementation timeframe, this may not be practical.
Quick Question Who should populate the DSL & DHS? The Configuration Management or Release Management team and why? Answer.
If the Release Management team exists, they should populate the DSL & DHS in parallel with populating the CMDB. If the team does not exist, the Configuration Management should populate them and then perform a handover when the Release Management team forms. After the CMDB, DSL & DHS are populated, the following should be implemented and tested: Security permissions CMDB backup and restoration services CMDB interfaces to other systems Any contingency plans. The population of the CMDB could become your first opportunity to manage discrepancies in your CI fleet. Migrating asset data from your existing CI register(s) to the new CMDB may expose losses/thefts in your CI fleet, which will need to be managed and resolved.

Changeover and considerations
Once operational, Configuration Management controls all CI changes. Considerations: Enough trained staff to avoid bottlenecks Start with important CIs Review o Activities against Plan o Resource effort o Data accuracy. The changeover to the new Configuration Management will be influenced by the decision of whether to carry out a phased implementation or „flick switch‟ approach. During phased or parallel implementation, any changes will need to advise both parallel processes to maintain accuracy. Once the new Configuration Management system is in operation, no changes to the CIs should be implemented with Configuration Management approval. This decision should be well advertised with the organization. After commencing operations, the Configuration Management process will continue to require management & staff commitment. If staff start to bypass the process (regardless of the reason), the benefits of the process will not be realized. This may be an ongoing challenge for the Configuration Manager. Quick Question As the Configuration Manager, you have realized that some staff are bypassing the Configuration management process. Broadly, what steps would you take to address this issue? Answer.
Traditionally when Configuration Management audits are mentioned, people normally think of auditing the CMDB (and DHS & DSL). Auditing the activities, procedures and expended effort is also important, as issues in these parts will lead to inaccurate CMDB data.

Activities for Configuration Management
Configuration Management planning Configuration identification and CIs Configuration control Configuration status accounting Configuration verification and audit CMDB Backups, housekeeping, etc.
The Configuration Management activities can be developed into specific procedures that will give instruction and guidance. The stakeholders for the configuration management procedures will include staff that are involved with introduction, maintenance and removal of CIs Any actual handbook will be found in the same area as the Configuration Management policy document. The procedural handbook can also be supplemented with a variety of flow charts/diagrams. The ultimate objective for the handbook is to detail how operational staff will actually carry out the day-to-day activities of Configuration Management.

Configuration Management planning
Reference existing procedures and plans Plan first 3-6 months in detail, next 12 months broadly 6 monthly reviews o Consider CMDB o Staff numbers & IT resources o Purge CI data to maintain efficient CM function o Review links with other ITSM processes o Review procedures handbook.
The Configuration Management plan needs to explain the rules for the process. In the rulebook, we need to see roles and responsibilities, naming conventions, interface details with third parties, CMDB management, related policies and process interfaces. Generally, the Configuration Management activity will grow over time as the number of CIs grows. This expected growth and future business needs should be considered at review times. Purging CI data may be considered as a means to trim the costs of the Configuration Management process. Configuration identification and CIs
Level of „independent change‟ All hardware & software CI or COMPONENT? Consider: o Auditing needs o Supply of CIs (packaged or parts).
It may be too simplistic to suggest a guide as to how “deep” the breakdown of CIs should go in an organization; but we need to start somewhere. As a rule, it may be helpful to consider identifying CIs to a level of detail that will allow independent change. That is, can I change that CI without affecting others? The depth of the CI levels will affect the size of your CMDB and the amount of effort to audit your CIs. If information at a low CI level would not be valuable – for example, if a laser printer cartridge is not manually exchanged independently or it seen as a consumable, then do not store. The approved CI levels outlined in the Configuration Management Plan should be regularly reviewed to ensure that the levels are adequate for the business. Choosing the right CI level is a matter of achieving a balance between the information available, the right level of control and the resources and effort needed to support it.

Attributes
Name Type Location Serial Number Version Number.
The attributes of a CI is the elements that allow us to define what the CI actually is. It is not possible to list all the attributes that a CI could have. However, we should consider keeping the number of attributes kept about a CI (or family of CIs) to as few as possible. NOTE: “as few as possible” is not designed to reduce our work load, but it helps us to focus on ensuring that we store the right amount of information and do not get overloaded with information that adds to value to the organization. Some other attributes include: Manufacturer Date received Date commissioned Product Manager (or CI owner). The VALUE is of an attribute is the answer to what the attribute asks. For example, if the attribute is “version” the value may be “1.0” or “2.0” Relationships
Asset register vs. Configuration Management Relationships provide dependency information. For example: o Parent/child relationship o A CI is connected to another o A CI uses another CI.
Now we reach the part that helps us to understand the principal difference between asset registers and the configuration management process. By creating, storing and maintaining relationship information between CIs the process adds real value to the IT department and (more importantly and indirectly) the organization. Relationships allow us to understand what CIs are dependent on other CIs.
Quick Question Which process will gain an incredible benefit from this relationship information? Answer:
Identification of configuration baselines

o Sound basis for future work (where are we now) o What will be affected by new RFCs o Fallback position Contain CI documentation as well info about themselves Use version numbering rather than live, next, old.
The creation and management of baselines serves a variety of purposes. The baseline may also provide a “trigger” for customer sign off regarding the configuration of a service (which could coincide with a review of Service Level Agreements). Baselines are particularly useful when a series of items are to be purchased, developed over an extended period. The baseline numbering scheme should be well thought out – as there may be many baselines in use at any one time (e.g. different countries, different regions, etc.). The Baseline will need to include associated documentation that was used in the creation of the base lined CIs Naming conventions
Apply to: o CIs, changes, baselines, releases and assemblies Unique Support existing organization conventions Permit growth Reflect relationships.
The creation of naming convention for software and hardware is not a simple task. However, once achieved, the convention will assist staff in identifying CIs and aid in the development of the CMDB and the overall control of CIs and other components.

Configuration control
Ensures that only authorized and identifiable CIs are recorded in the CMDB upon receipt Procedures need to cover all stages. Examples: o Registration o Updates (RFC to CI relationship) o Decommissioning o Data integrity protection.
The configuration control procedures should protect the integrity of the organization‟s data, systems and processes by ensuring that unauthorized changes are virtually impossible. The configuration management procedures handbook will need to inform IT staff how to manage CIs, their attributes, relationships and events throughout a CIs life in an organization. During the development of the procedures, the author will need to consider the existing ITSM procedures and the existing IT service management processes, especially Change and Release Management. Focus on avoiding duplication in procedures and encouraging input from other process managers. Configuration Management is widely utilized by other ITSM processes and procedures should not developed in isolation. We will step through some key on-going control processes: Registration, Updating, Removing, and Protection. CI Registration
Secure environment Verify received goods Consider procurement processes Off the shelf In-house developed o When to register? (Development, test, production).
The registration of new CIs should be conducted in secure environment, as assets are vulnerable to loss/theft during handover from supplier to customer. New goods should be verified upon receipt. Registration procedures should incorporate existing procurement processes to reduce duplication. Assembly and delivery procedures from suppliers could be reviewed to potentially incorporate elements of your registration procedures. For example, bar coding of new equipment by the supplier prior to delivery. The procedures may need to manage off-the-shelf equipment as well as in-house developed CIs. For software developed in-house, you may consider registering software either at the development, acceptance test or production stage. The management overhead cost on application development staff in maintaining an in-house system‟s CI status needs to be considered.

ITIL® V2 Practitioner: Release and Control (IPRC) Complete Certification Kit – Second Edition
CI Updating
Consider the entire CI lifecycle Be able to update: o CIs o Attributes o Relationships o Events Seek linkages with other system for update automation.
There is a natural progression for the status of a CI as it moves through its life cycle (progression from procurement to perish!). Ideally, we would rely on technology to a large degree to carry out automated discovery and updates of CIs. This is also true for related documentation (e.g. document management systems), licenses, etc. Procedures will need to detail how to update statuses of CIs, attributes, relationships and events. Examples include new documentation for CIs and new license agreements for off-theshelf software. Consider the ability to update CIs „owners‟. The staff that manage or have responsibility for CIs, and may leave their current role or leave the organization. The ability to automate this task with a linkage between the CMDB and an organizations‟ HR system is advantageous. CI Removal
Same considerations as CI registration Consider existing disposal methods Another vulnerable period for CIs.
Incorporating existing disposal procedures not only reduces duplication but also ensures any legal obligations will be met; as such disposal procedures which are generally built on “business practices” – not necessarily IT practices. CI removal (or disposal) is another vulnerable period for loss/theft so security measures are encouraged.

Integrity of configurations
Protection of CIs and their components Covering o Procurement o Storage, Dispatch, Receipt o Disposal For software CIs o Virus protection o Environmental considerations.
The principle purpose for this activity is the ability to “recreate” a known good configuration at some point in the future. Without considering how the CIs will be protected during all aspects of the CIs life – then the ability to do this will be severely compromised. Even to the point of software CIs and the requirement to refresh magnetic data and protection from disaster. Configuration Status Accounting
Status accounting report generation o Who can request a report o How to request a report or how to generate report independently o Report formats o Report publishing rules.
Status accounting reports on the current, previous and planned states of CIs. The procedures for developing status accounting reports may include: Verifying who can request a report How to request a report How to run a report Report formats: are they fixed or custom-made and how to generate them Publishing reports: dissemination procedures (public or private access). Configuration verification and audit
Other ITSM processes depend upon an accurate CMDB Detail o Audit frequency o Depth of audit o Staff involved Use automated tools (detail instructions) Log and manage discrepancies.
The integrity of the CMDB should be audited as numerous ITSM process assume that the CMDB is accurate. Procedures for carrying out such audits should detail (at least) the audit frequency, depth of audit, staff involved and steps for sign-off and communicating audit outcomes. Each approved and released CI should have an approved RFC associated with it.

ITIL® V2 Practitioner: Release and Control (IPRC) Complete Certification Kit – Second Edition
Use of automated tools for auditing is encouraged and instructions for using such tools should be detailed. Procedures on logging and managing discrepancies and conducting investigations into missing CIs should be detailed. These procedures may include managing any issues with the procedures and the behavior of personnel. Any internal security investigation procedures may also be incorporated. CMBD backup, housekeeping Back-up CMDB (restore procedures) Archiving information Frequency and retention policy Retention based on usefulness Regular checks to remove obsolete/redundant CI information. Archiving is a distinctively separate activity from backing up the CIs. A CI may become obsolete and is no longer required in the production environment. However, information about the CI may be needed for financial and security auditing reasons. Therefore, procedures should be developed to archive and later review this data – if called upon. Configuration Management - Service
As a service, CM can add value by providing these recommended services: Regular & adhoc reporting Advice on policy & procedures Advice on configuration complexity Auditing service Library service License management. Once Configuration Management is established, the team should help to provide a variety of services to other ITSM processes and business units. Providing a „value-added‟ service will enhance the IT organization‟s reputation by moving from just day-to-day Configuration Item (CI) management to pro-active CI management.

Depending on your organization, the Configuration Management tool needs to effectively support: The lifecycle of CIs from beginning to end Provide support to the other ITSM processes Provide flexible reporting tools Allow easy auditing of CIs Store and show relationships between CIs Store events associated with CIs. Regardless of the size of an organization, an automated CMDB will provide a more efficient service than a paper-based service. Ideally, the CMDB will be linked to the DSL and other software development configuration management tools. If this is not possible, the CMDB should at least allow CI information to be exchanged between the software development configuration management tools and it. For auditing purposes, if the DSL is not integrated with the CMDB it may be worth automating the comparison of the DSL contents with the CMDB. Accurate and detailed auditing tools will mean that staff focus on managing exceptions, rather than doing the audit itself.

Relationships – Release and Control Processes
Configuration Management Configuration Management is an integral part of all other Service Management processes. With current, accurate and comprehensive information about all components in the infrastructure the management of change, in particular, is more effective and efficient. Change Management can be integrated with Configuration Management. As a minimum it is recommended that the logging and implementation of changes be done under control of a comprehensive Configuration Management system and that the impact assessment of changes is done with the aid of the Configuration Management system. All change requests should therefore be entered in the Configuration Management Database (CMDB) and the records updated as the change request progresses through to implementation. The Configuration Management system identifies relationships between an item that is to be changed and any other components of the infrastructure, thus allowing the owners of these components to be involved in the impact assessment process. Whenever a change is made to the infrastructure, associated Configuration Management records should be updated in the CMDB. Where possible, this is best accomplished by the use of integrated tools that update records automatically as changes are made. The CMDB should be made available to the entire Service Support group so that incidents and problems can be resolved more easily by understanding the possible cause of the failing component. The CMDB should also be used to link the incident and problem records to other appropriate records such as the failing Configuration Item (CI) and the user. Release Management will be difficult and error prone without the integration of the Configuration Management process. The Service Delivery processes also rely on the CMDB data. For example: Service Level Management needs to identify components that combine together to deliver the service so that underpinning agreements can be set up Financial Management for IT needs to know the components utilized by each business unit especially when charging is in place IT Service Continuity and Availability Management need to identify components to perform risk analysis and component failure impact analysis.

ITIL® V2 Practitioner: Release and Control (IPRC) Complete Certification Kit – Second Edition
Change Management The Change Management process depends on the accuracy of the configuration data to ensure the full impact of making changes is known. There is therefore a very close relationship between Configuration Management, Release Management and Change Management. Details of the change process are documented in SLAs to ensure that users know the procedure for requesting changes and the projected target times for, and impact of the implementation of changes. Details of changes need to be made known to the Service Desk. Even with comprehensive testing there is an increased likelihood of difficulties occurring following change implementation wither because the change is not working as required or expected, or because of queries on the change in functionality. The Change Advisory Board (CAB) is a group of people who can give expert advice to the Change Management team on the implementation of changes. This board is likely to be made up of representatives from all areas within IT and representatives from business units.
Release Management Changes may often result in the need for new hardware, new versions of software, and/or new documentation, created in-house or bought in, to be controlled and distributed, as part of a new „packaged release‟. The procedures for achieving secure, managed rollout should be closely integrated with those for Change Management and Configuration Management. Release procedures may also be an integral part of Incident Management and Problem Management, as well as being closely linked to the CMBD in order to maintain up-to-date records.

This diagram shows the complexity of the relationships and the processes involved in Release and Control management activities. The release process and the configuration management process are first stimulated by the change management processes. This does not mean that the Change Management process has precedence though. ITIL is very clear however that the Configuration Management process should not be implemented before Change Management. The User, in this instance it may be the Customer of the IT Department or a User in the organization, would request a change in the form of a RFC. Change Management would accept or reject this change depending on the information and any assessments that have been carried out. If the change goes ahead, as it does in this example, for redoing a desktop environment, we need to know look at the available equipment needed. We can look in both the CMDB and the DSL / DHS. The DSL / DHS is where the physical hardware and software will come from. This of course is recorded in the CMDB. The release management process will ensure that the hardware and software are correctly built into releases and distributed and installed across the infrastructure according to the change management plans. Other processes and functions will be included in this as necessary. Tools are often thought of as complex and expensive. However, there is no rule that says that a simple database cannot be used to control information about Configuration Items or that a paper-based form cannot be the beginning point for all infrastructure changes.

What determines the complexity? Tools are generally used to help us deal with volumes of work that could not be dealt with without them! Tools help us to overcome resource shortages (principally money and people). They are becoming ingrained in most organizations, as our world becomes increasingly IT complex, with multiple vendors and growing acceptance of international standards. Tools deliver the ability to centralize & automate activities, analyze data, identify trends and take preventative measures.

Release and Control Support Tools Quick Question Which comes first – a process or the tools? Answer:
Tools are often thought of as complex and expensive. However, there is no rule that says that a simple database cannot be used to control information about Configuration Items (CIs), or that a paper-based form cannot be the beginning point for all infrastructure changes. Tools are generally used to help us with volumes of work that could not be dealt with without them. Tools help us overcome resource shortages (principally money and people). They are becoming ingrained in most organizations, as our world becomes increasingly IT complex, with multiple vendors and growing acceptance of international standards. Tools deliver the ability to centralize and automate activities, analyze data, identify trends and take preventative measures. Tool selection
Non-core selection criteria Supplier o Reputation/history, Support focus, Training & consulting, Future plans (new modules?), References Ongoing costs o Customizations, upgrades, maintenance Adaptability o Flexibility to support the changing organization.
Often overlooked these three elements must be part of any selection criteria exercise. We have referred to them as “non-core” as they are not specifically linked to a particular process/activity. Of these, the issue of adaptability has the potential to completely ruin the tool selection process. What was an excellent decision at the time can quickly become a poor choice, when tools cannot be adapted to meet the (inevitable) organizational changes (e.g. Mergers, takeovers, expansion into new territories/countries).

Tool selection 80% fit on requirements Delivery on mandatory requirements Out of the box “ITIL compliance” Low/known administration costs Low/known maintenance costs. This list gives us some elements to consider when looking at the actual service management software itself. The list is not compulsory, but serves as a guide. The best demonstration of this point is the “ITIL compliance” point. You would not reject a tool simply because it did not have a sticker on the box. Costs associated with tools:
Tool costs: o Back end o Front end: licenses Equipment costs: o Server / disk space o Network capacity o Desktop requirements? Training: o Support staff o Tool maintenance staff Consulting: o Tool configuration o (Future) changes: adaptability?
The list allows us to appreciate that while there are obvious costs associated with the use of service management tools, hidden costs that can be overlooked. An important consideration that is not mentioned above is the increased likelihood that the deployment of a tool within the organizational infrastructure could create service outages. This is a real risk for the organization and while the supplier will promote their products‟ stability and excellent performance at other sites, will they offer any guarantee that the tool will not create such outages?

Process Organization and Design Process and Procedures The difficulty with defining what a process is, what a procedure is, etc. is made complicated due to peoples backgrounds, experiences and Wikipedia (http://en.wikipedia.org) defines a process as “naturally occurring or designed sequence of operations or events, possibly taking up time, space, expertise or other resource, which produces some outcome. A process may be identified by the changes it creates in the properties of one or more objects under its influence.” Whereas the same resource describes a procedure as “a series of activities, tasks, steps, decisions, calculations and other processes, that when undertaken in the sequence laid down produces the described result, product or outcome. Following a procedure should produce repeatable results for the same input conditions. It is interesting to note that even in the definition of what a procedure is the word process appears! Process, Procedure and Work Flow swim lanes
Swim lanes are similar to flow charts, with the added information of explicitly showing WHO will do a process step. The “who” can be an individual, department or organization. In this simple example, we can see the start of an incident and how an organization may define the flow of activities and the “HAND OFF” points. The hand off points give us clear places to look at with regard to poor communication or a lack of understanding. Important to note that this example is very simple and that the standard flow chart icons can be used (not used in this example).

Brainstorming techniques
Freewheeling Carousel One-Two-Six Slip Method
Creating processes and procedures can often require input and ideas from a variety of people. Here are some basic techniques to help generate ideas that can then be used as the starting point for creation. Freewheeling – Simply calling out ideas and exact words are written down Carousel – Create a series of questions/topics on sheets of paper spread around a room. Small groups spend a few minutes at one sheet, before they move on to the next. One-Two-Six – each person writes down one idea. Participants pair off to share ideas and select one. Participants form groups of six to share their ideas and select one. Slip Method – Small groups, ideas are written on cards (slips) and then organized into groups or themes. Creativity technique
S - substitute C - combine A - adapt M - modify P - put to another use E - eliminate R - reverse
This technique is generally used in manufacturing, when looking at creation of a new product. The SCAMPER points can be addressed directly or used as prompts for lateral thinking. Note: the letters do not represent a flow that has to be followed, but are prompts for creativity. Let‟s try to apply the technique to the creation of a procedure. Substitute – replace all or parts of an existing procedure with all or parts of a procedure defined by a governing body Combine – create joint procedures with suppliers and distributors Adapt - use outside consultants to develop all procedures Modify – use diagrams only (no long text based descriptions) Put to another use – sell developed procedures to external organizations Eliminate – rely on word of mouth and commonsense Reverse – develop an industry framework.

RACI Model
The concept of this technique is similar to SWIM LANES. Both are designed to show WHO is involved. The RACI model extends the swim lanes by recognizing the different types of action required for each step of the procedure. The RACI model helps show how a process actually does work end to end across several functional groups. R – Responsibility (actually does the work for that activity but is responsible to the function or position that has an “A” against it. A – Accountability (is made accountable for ensuring that the action takes place, even if they might not do it themselves). C – Consult (advice / guidance / information can be gained from this function or position prior to the action taking place). I – Inform (the function or position that is told about the event after it has happened). General Rules: • Only 1 “A” per Row (ensures accountability, more than one “A” would confuse this) • At least 1 “R” per Row (shows that actions are taking place)

When the technique is applied, we can analyze the table both VERTICALLY and HORIZONTALLY. Vertical analysis can help us identify roles or groups that we may be over-reliant on. If multiple columns have identical entries, than there may be a potential to merge those groups from an activity point of view. Horizontal analysis allows us to identify events that cross many functional roles/groups (which may be an indication of high bureaucracy or of potential for breakdowns in communication (hand offs).

Change Management
The Process responsible for controlling the Lifecycle of all Changes. The primary objective of Change Management is to enable beneficial Changes to be made, with minimum disruption to IT Services.
Change Record
A Record containing the details of a Change. Each Change Record documents the Lifecycle of a single Change. A Change Record is created for every Request for Change that is received, even those that are subsequently rejected. Change Records should reference the Configuration Items that are affected by the Change. Change Records are often stored in a Configuration Management Database.
Classification The act of assigning a Category to something. Classification is used to ensure consistent management and reporting. CIs, Incidents, Problems, Changes etc. are usually classified. Closure

Configuration The Activity responsible for ensuring that adding, modifying or removing a CI is Control properly managed, for example by submitting a Request for Change or Service Request. Configuration The Activity responsible for collecting information about Configuration Items and Identification their Relationships, and loading this information into the CMDB. Configuration Identification is also responsible for labeling the CIs themselves, so that the corresponding Configuration Records can be found. Configuration Any Component that needs to be managed in order to deliver an IT Service. Item (CI) Information about each CI is recorded in a Configuration Record within the CMDB and is maintained throughout its Lifecycle by Configuration Management. CIs are under the control of Change Management. CIs typically include hardware, software, buildings, people, and formal documentation such as Process documentation and SLAs. Configuration The Process responsible for maintaining information about Configuration Items Management required to deliver an IT Service, including their Relationships. This information is managed throughout the Lifecycle of the CI. The primary objective of Configuration Management is to underpin the delivery of IT Services by providing accurate data to all IT Service Management Processes when and where it is needed. Configuration Management Database (CMDB)
A Database used to manage Configuration Records throughout their Lifecycle. The CMDB records the Attributes of each CI, and Relationships with other CIs. A CMDB may also contain other information linked to CIs, for example Incident, Problem or Change Records. The CMDB is maintained by Configuration Management and is used by all IT Service Management Processes.
Configuration The hierarchy and other Relationships between all the Configuration Items that Structure comprise a Configuration. Customer

Release
actually changed since the last Release. A Delta Release is also referred to as a partial Release.
Environment
A subset of the IT Infrastructure that is used for a particular purpose. For Example: Live Environment, Test Environment, Build Environment. It is possible for multiple Environments to share a Configuration Item, for example, Test and Live Environments may use different partitions on a single mainframe computer. Also used in the term Physical Environment to mean the accommodation, air conditioning, power system etc.
Full Release
A Release that includes all Components of a Release Unit, including those that have not changed.
Impact
A measure of the effect of an Incident, Problem or Change on Business Processes. Impact is often based on how Service Levels will be affected. Impact and Urgency are used to assign Priority.
Incident
An unplanned interruption to an IT Service or reduction in the Quality of an IT Service. Any event which could affect an IT Service in the future is also an Incident. For example Failure of one disk from a mirror set.
Lifecycle
The various stages in the life of a Configuration Item, Incident, Problem, Change etc. The Lifecycle defines the Categories for Status and the Status transitions that are permitted. For example: The Lifecycle of an Application includes Design, Build, Test, Deploy, Operate etc. The lifecycle of an Incident includes Detect, Respond, Diagnose, Repair, Recover, Restore. The lifecycle of a Server may include: Ordered, Received, In Test, Live, Disposed etc.
Priority
A Category used to identify the relative importance of an Incident, Problem or Change. Priority is based on Impact and Urgency, and is used to identify required times for actions to be taken. For example the SLA may state that Priority2 Incidents must be resolved within 12 hours.
Process

Service Level Agreement (SLA)
An Agreement between an IT Service Provider and a Customer. The SLA describes the IT Service, documents Service Level Targets, and specifies the responsibilities of the IT Service Provider and the Customer. A single SLA may cover multiple IT Services or multiple customers.
Service Request
A request from a User for information or advice, or for a Standard Change. For example to reset a password, or to provide standard IT Services for a new User. Service Requests are usually handled by a Service Desk, and do not require an RFC to be submitted.
System
A number of related things that work together to achieve an overall Objective. For example: A computer System including hardware, software and Applications. A management System, including multiple Processes that are planned and managed together. For example a Quality Management System. A Database Management System or Operating System that includes many software modules that are designed to perform a set of related Functions.
Urgency
A measure of how long it will be until an Incident, Problem or Change has a significant Impact on the Business. For example a high Impact Incident may have low Urgency, if the Impact will not affect the Business until the end of the Financial Year. Impact and Urgency are used to assign Priority.
User
A person who uses the IT Service on a day-to-day basis. Users are distinct from Customers, as some Customers do not use the IT Service directly.
Version
A Version is used to identify a specific Baseline of a Configuration Item. Versions typically use a naming convention that enables the sequence or date of each Baseline to be identified.
Workaround
Reducing or eliminating the Impact of an Incident or Problem for which a full Resolution is not yet available. For example by restarting a failed Configuration Item. Workarounds for Problems are documented in Known Error Records. Workarounds for Incidents that do not have associated Problem Records are documented in the Incident Record.
