The Information Technology Infrastructure Library™ (ITIL) offers a systematic approach to the delivery of quality IT services. ITIL was developed in the 1980s and 1990s by CCTA (Central Computer and Telecommunications Agency, now the Office of Government Commerce, OGC), under contract to the UK Government. Since then, ITIL has provided not only a best practice based framework for IT management, but also an approach and philosophy shared by the people who work with it in practice. ITIL has now been updated twice, the first time in 2000-2002 (V2), and the second time in 2007 (V3).
The ITIL Qualification Scheme uses a system that enables an individual to gain credits for each exam they take. Once candidates have accumulated a sufficient number of credits they can be awarded the ITIL Expert in IT Service Management. There are four levels within the scheme: § Foundation Level § Intermediate Level (Lifecycle Stream and Capability Stream) § ITIL Expert § ITIL Master
