ITIL & ISO 20000 Blog

ITIL and ISO/IEC 20000 History: Parallel Worlds

I was interested in the origins of ITIL and ISO 20000, and began looking it up on the internet and in literature. There are bits and pieces of info here and there, rumors and info of questionable quality on forums and blogs. I have managed to collect this information and put it in a table in an organized fashion for the convenience of anyone who might share the interest.

Since some of the sources are not 100% verified, please feel free to comment if you have an update or complementary info.

Some myths (Falkland war origins of ITIL) are funny and believable, but denied by the authors.

The role of IBM and its Information Systems Management Architecture (ISMA) is pretty vague; even the stakeholders from that time do not agree on the degree to which it influenced ITIL. I am ready to believe that ISMA played a significant role in the forming of ITIL V1, but that vehicle quickly took the road and went many miles from its origins.

ITIL_timeline

The late Margaret Thatcher was first elected Prime Minister in 1979. The fact was that the UK Government’s IT budget was extremely large and difficult to control, and it is quite reasonable to think that ITIL development was related to cost-cutting, efficiency-driven policy of that time.

As for ISO 20000, information on its history is even scarcer. I thought it would be fun to see major milestones and deliverables side by side in a single table:

ITILISO/IEC20000
1986CCTA (UK Government’s Central Computer and Telecommunications Agency) authorized a program to develop a common set of operational guidance with the objective of increasing efficiencies in Government IT.
1988GITMM – Government Infrastructure Management Method was formalized and issued as guidelines for Government IT operations in the UK focused on Service Level Management. Also in 1988, the development team was expanded and work continued on Cost, Capacity, and Availability.
1989GITMM title proved inadequate. It is not a method, and the “G” was making it unmarketable outside of government. Finally, it received a new name: IT Infrastructure Library – ITIL.
1989First ITIL book published, Service Level Management, Help Desk (incorporating the basic concepts of Incident Management), Contingency Planning, and Change Management.
