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:
