 ITIL & ITSM
 IT Infrastructure Library
The Information Technology
Infrastructure Library (ITIL) is a set of concepts and
techniques for managing information technology (IT) infrastructure,
development, and operations. ITIL
is built around a process-model
based view of controlling and managing operations often credited to W.
Edwards Deming[citation needed].
ITIL is published in a series of books, each of which cover an IT
management topic. The names ITIL and IT Infrastructure Library are
registered trademarks of the United Kingdom's Office of Government
Commerce (OGC). ITIL gives a detailed description of a number of
important IT practices with comprehensive checklists, tasks and
procedures that can be tailored to any IT organization.
In December
2005, the OGC issued notice of an ITIL refresh,[6] commonly known as
ITIL v3, which became available in May 2007. ITIL v3 initially includes
five core.
These publications update much of the current v2 and extend the scope
of ITIL in the domain of service management.
IT Service Management
Information Technology
Service Management (ITSM) as a concept is related but not
equivalent to ITIL which, in Version 2, contained a subsection
specifically entitled IT Service Management (ITSM). (The five volumes
of version 3 have no such demarcated subsection). The combination of
the Service Support and Service Delivery volumes are generally
equivalent to the scope of the ISO/IEC 20000 standard
(previously BS 15000).

ITIL V2 & V3
ITIL Publications
ITIL originated
as a collection of books each covering a specific practice within IT
Service Management. In order to make ITIL more accessible (and
affordable), one of the aims of ITIL v2 was to consolidate the
publications into logical 'sets' that grouped related process
guidelines into the different aspects of IT management, applications
and services.
While the ITIL Service Management sets (Service Support and Service
Delivery) are by far the most widely used, circulated and understood,
ITIL provides a more comprehensive set of practices.
ITIL Version 2
The eight ITIL v2 books
and their disciplines are:
The IT Service Management sets
1. Service Delivery
2. Service Support
Other operational guidance
3. ICT Infrastructure Management
4. Security Management
5. The Business Perspective
6. Application Management
7. Software Asset Management
To assist with the implementation of ITIL practices a further book was
published providing guidance on implementation (mainly of Service
Management):
8. Planning to Implement Service Management
More recently these books have been supplemented with guidelines for
smaller IT units:
9. ITIL Small-Scale Implementation
ITIL
Version 3
ITIL v3, published in May 2007, comprises 5 key
volumes:
1. Service Strategy
2. Service Design
3. Service Transition
4. Service Operation
5. Continual Service Improvement .
