Introduction

This paper discusses the various elements of Information Technology Infrastructure Library (ITIL). It refers to a collection of information service management (ITSM), which focuses on aligning information technology services with business needs (Fry 5). ITIL is published in a sequence of five major publications, with each stage covering the lifecycle of an ITSM. According to Vetterani (7), ITIL highlights ISO/IEC 20000, which is the International Service Management Standard for Information Technology. However, there is a difference between the two. ITIL highlights the procedures, processes, checklists and tasks, which are not specific to an organization. ITIL enables organizations to launch a baseline for implementing, planning and measuring strategies. According to De Jong and Kolthof (8), ITIL is deployed in demonstrating the fulfillment of the strategy and measuring improvement. It is also imperative to recognize that ITIL, as an acronym, is a registered trademark of United Kingdom’s Cabinet Office. Because of this move, the ownership of ITL is now listed as being with the HM Government instead of OGC.

History of ITIL

As a reaction to the increasing reliance on information technology, the Central Computer and Telecommunications Agency (CCTA) of the government of UK in the 1980s developed a collection of recommendations. The CCTA recognized that without standard practices, both the private sector contracts and government agencies had begun developing their IT management standards independently. According to Fry (3), ITIL was established as a set of books, each of which covered a specific practice in the I

nformation Technology Service Management (ITSM). The number of books rapidly increased to more than 30 volumes after the first publications between 1989 and 1996. In 2000, in order to make ITIL more available and affordable, ITIL v2 combined the publications into 8 sets, which grouped associated process standards. The main objective of this was to match the various aspects of IT management, services and applications. The sets for Services Management that included Service Support and Service Delivery were the most widely deployed, understood and circulated of all the ITIL version 2 publications.

In April 2001, the CCTA was integrated into the Office of Government Commerce (OGC), which was an office of United Kingdom Treasury. This was followed by the publication of ITIL version 2 in 2006. In May 2007, the merged organization issued version 3 of the ITIL that was also known as ITIL Refresh Project. ITIL v3 comprised of 26 functions and processes that are now grouped into 5 volumes. The volumes are arranged around the notion of service lifecycle. ITIL v3 is also recognized as ITIL 2007 Edition. OGC formally announced that the certification of ITIL v2 would be withdrawn and introduced a key consultation pertaining how to proceed. Recently, in 2011, the ITIL 2011 Edition was published. It provided an update to the previous edition of 2007. However, OGC is no longer the owner of ITIL because of the merging of OGC into the UK’s Cabinet Office. The HM Government owns the ITIL 2011 edition.

the withdrawal period on June 2011. The 2007 edition offers a more holistic view of the full life cycle of services. It covers complete IT organization and supporting components needed, in order to deliver sufficient services to the customer. On the other hand, version 2 focuses on particular activities that directly linked to service support and delivery. Most of activities provided by v2 remained unchanged in the 2007 edition, though some considerable changes in expressions were launched to enable the extension.

The HM government has published a summary of changes. In relation to the previous edition, the ITIL 2011 edition comprises of five primary publications that include service strategy, service design, service transition, service operation and service management. According to De Jong and Kolthof (6), the 2011 Edition is a revision of the ITIL framework, which addresses considerable additional standards by highlighting the official processes that were initially meant, though not identified.

Service Strategy

As the origin and central point of the ITIL Service Lifecycle, the Service Strategy (SS) offers standards on prioritization and guidance of service-provider investments in services. In general, the service strategy focuses on assisting IT organizations to develop and improve over long-term. In the two scenarios, service strategy depends tremendously on market-driven framework. The major areas constituted in the services strategy include business-case development, service value definition, service assets, service provider types and market analysis. The various process covered in the service strategy include Service management, service portfolio management, financial management for IT services, demand management and business relationship management.

Financial Management for IT services is an aspect of best practices specified by ITIL. The major objective of process of ITIL is to provide a cost-effective and accurate stewardship of IT resources and assets deployed in IT services. It is deployed in planning, controlling and recovering the costs used in offering IT services agreed, and negotiated to in the service-level agreements (SLAs). In general, the essential objective of financial management for IT services is to provide an ultimate transparent evaluation of what an organization is expending on IT resources. In most scenarios, this evaluation of effectiveness is deployed to develop metric-based and intelligent cost-cutting strategies. For an internal information technology organization, the objective can be to provide a cost-effective stewardship of the information technology resources and assets used in offering IT services. For an outsourced IT company or a separate entity organization, the objective of financial management is to enable full accounting of resources used on providing IT services in order to be capable to attributing the costs to the services provided to customers.

Financial management for IT services has three sub-processes that include budgeting, IT accounting and charging. Budgeting allows organizations to plan for forthcoming expenditure. Therefore, the organizations cut down the threat of over-spending and ensure that revenues are available to cover the predicted expenditure. In addition, budgeting enables organizations to contrast the real costs with the initial predicted costs to enhance the reliability of budgeting forecasts.

IT accounting is related to the amount of cash spend in delivering IT services. IT accounting enables organizations to perform different financial evaluations, in order to measure
