338/365 – ITIL

The Information Technology Infrastructure Library (ITIL), is a set of practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business.

In its current form (known as ITILv3 and ITIL 2011 edition), ITIL is published in a series of five core publications, each of which covers an ITSM lifecycle stage.

ITILv3 underpins ISO/IEC 20000 (previously BS15000), the International Service Management Standard for IT service management, although differences between the two frameworks do exist.

ITIL describes procedures, tasks and checklists that are not organization-specific, used by an organization for establishing a minimum level of competency.

It allows the organization to establish a baseline from which it can plan, implement, and measure. It is used to demonstrate compliance and to measure improvement.

The names ITIL and IT Infrastructure Library are registered trademarks of the United Kingdom’s Office of Government Commerce (OGC) – now part of the Cabinet Office. Following this move, the ownership is now listed as being with HM Government rather than OGC.

Overview of ITIL v3  

ITIL v3 is an extension of ITIL v2 and fully replaced it following the completion of the withdrawal period on 30 June 2011.

ITIL v3 provides a more holistic perspective on the full life cycle of services, covering the entire IT organisation and all supporting components needed to deliver services to the customer, whereas v2 focused on specific activities directly related to service delivery and support.

Most of the v2 activities remained untouched in v3, but some significant changes in terminology were introduced in order to facilitate the expansion.

A summary of changes has been published by HM Government. In line with the 2007 edition, the 2011 edition consists of 5 core publications – Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement.

ITIL 2011 is a major update to the ITIL framework that addresses errors and inconsistencies.   There are 26 processes listed in ITIL 2011 edition and described below that shows which core publication provides the main content for each process.

ITIL v3 has five volumes, published in May 2007 and updated in July 2011 (2011 edition) for consistency:

1.ITIL Service Strategy

 2.ITIL Service Design

3.ITIL Service Transition

4.ITIL Service Operation

5.ITIL Continual Service Improvement
