I have looked arround the web a little and was bored with the general ITIL history articles found on the web. There are a few inconsistencies and interesting myths circling around, like the one on the Falklands war and possible general war threat with Argentina, which are denied by the authors of V1.
The fact that Mrs. Thatcher came to power in 1979. and that ICT budget of UK government exceeded 8 bil. UK pounds was probably one of initiators of GITMM (or GITIMM, not sure).
So, here is a short list of important milestones:
1972: IBM starts research on quality service delivery called information Systems Management Architecture (ISMA).
1980: IBM publishes Volume I of the IBM Management series titled "A management System for the Information Business", first public edition of ISMA.
1986: CCTA authorizes a program to develop a common set of operational guidance with the objective of increasing efficiencies in Government IT.
1988: "Government Infrastructure Management Method (GITMM)", is formalized and issued as 'guidelines' for Government IT operations in the UK focused on Service Level Management. Same year, the development team was expanded and work continued on Cost, Capacity, and Availability.
1989: GITMM title is inadequate. It is not a method, (last M), and it should lose its G letter in order to be marketable out of government. Renamed to ITIL.
1989: First 'ITIL' book published, Service Level Management, then Help Desk (incorporating the concepts of Incident Management), Contingency Planning, and Change Management. Books had 50-70 pages.
1990: Problem Management, Configuration Management and Cost Management for IT Services published.
1991: Published - Software Control & Distribution, on 89 pages.
1992: Availability Management, 69 pages.
1996: (July) First ITIL Service Manager class delivered in US by US company, ITSMI, 16 attended, 10 candidates, nine passes, one distinction, first US company authorized as an ITIL accredited course provider - ITSMI.
1997: Customer focused update to the Service Level Management book, 106 pages.
1997: ITIMF legally becomes what we know today as the IT Service Management Forum (itSMF UK).
2000: Service Support V2 published, 306 pages.
2001: Service Delivery V2 published, 376 pages.
2001: CCTA became a part of the Office of Government Commerce (OGC)
2002: Application Management, 158 pages, Planning to Implement IT Service Management, 208 pages and ICT Infrastructure Management, 283 pages, published.
2003: Software Asset Management, 146 pages, published .
2004: Business Perspective: The IS View on Delivering Services to the Business, published, 180 pages.
2006: (June) ITIL Glossary V2 published
2006: (June) APM Group Limited announced as preferred bidder of ITIL accreditation & certification program, over the itSMF International (expectant winner)
2007: (May) ITIL V3 five core books published.
Let's analyse this timeline a bit:
ITIL V1 was rather similar to IBM's ISMA, especially in support/delivery domain. Core ITIL V2 books did not differ much from ITIL V1. Only a few processes were altered slightly, but the focus and perspective was pretty much unchanged. And this process lasted for some 20 years.
ITIL V3 approximately doubled the scope, almost tripled the number of processes and functions and introduced a few new dimensions and perspectives. We have the first set of core books now, but a lot of time will be needed to develop all the complementary books, to groom and mature the training materials and to polish best implementation practices.
In the meantime, ITIL V2 books are still at our disposal for reference and for completing the ongoing implementations.
