ITIL is the only consistent and comprehensive documentation of best practice for IT Service Management. Used by many hundreds of organisations around the world, a whole ITIL philosophy has grown up around the guidance contained within the ITIL books and the supporting professional qualification scheme.
ITIL consists of a series of books giving guidance on the provision of quality IT services, and on the accommodation and environmental facilities needed to support IT. ITIL has been developed in recognition of organisations' growing dependency on IT and embodies best practices for IT Service Management.
The ethos behind the development of ITIL is the recognition that organisations are becoming increasingly dependent on IT in order to satisfy their corporate aims and meet their business needs. This leads to an increased requirement for high quality IT services.
ITIL provides the foundation for quality IT Service Management. The widespread adoption of the ITIL guidance has encouraged organisations worldwide, both commercial and non-proprietary, to develop supporting products as part of a shared 'ITIL Philosophy'.
