Some details about ITIL v3

ITIL started in the 80s with close to 40 publications

When v2 following in 2000-2002 it was still large and complex and consisted of eight books in total. These Books talk about what needs to be done for good IT Service management.

It has got a more modular accredited path that is easier to navigate and understand. It also provides tactical and operational guidance. ITIL v3 gives more prominence to the strategic ITIL guidance which is more relevant to the senior staff. This version of the system is aligned with the ISO20000 standard made for IT service management.

ITIL v2 has close to 700 different pages of key publications where the newer version has 1400 pages distributed through 5 critical books of the service lifecycle, ie the service strategy, service transaction, service design, service operation, and continual service improvement.
