ITIL 2007 Edition (previously known as version 3) is an extension of ITIL v2 and fully replaced it following the completion of the withdrawal period on 30 June 2011.[4] ITIL 2007 provides a more holistic perspective on the full life cycle of services, covering the entire IT organization 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 2007, 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 five core publications – Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. ITIL 2011 is an update to the ITIL framework that addresses significant additional guidance with the definition of formal processes which were previously implied but not identified, as well as correction of errors and inconsistencies.
There are twenty-six processes listed in ITIL 2011 edition and described below that shows which core publication provides the main content for each process.
ITIL 2007 has five volumes, published in May 2007 and updated in July 2011 as ITIL 2011 for consistency:
