The ITIL framework is split into 5 core sections:
These sections are documented in five volumes which cover the ITIL service lifecycle, beginning with identification of customer needs and ending with an evaluation and improvement stage.
There are five levels of ITIL certification:
These levels gradually give you a deeper understanding of ITIL. The level you go up to entirely depends on you and your organisation’s need to better understand the ITIL framework. The Foundation level will offer you a general understanding of the key elements, concepts and terminology of the ITIL life cycle, including how each stage links to one another and their wider contribution to service management.
Expert and master levels are for those who want to demonstrate knowledge of ITIL in its entirety, including the ability to demonstrate knowledge and understanding of how and why you have personally implemented ITIL frameworks in your organisation. The levels in between help build on the knowledge you gained during the Foundation level. More information can be found on the individual training pages.
