ITIL® (Information Technology Infrastructure Library) is a set of concepts and policies for managing IT infrastructure, development and operations. It is by far the most widely accepted and the most comprehensive documentation of best practices for IT service management. Published in a series of books, ITIL® exhibits a number of important IT practices with comprehensive checklists, tasks and procedures that can be tailored to any IT organization.
Having been adopted by thousands of organizations worldwide, ITIL® has already nurtured a whole new ITIL® philosophy, built around the guidance contained within the books and supported by a comprehensive certification scheme, accredited training organizations, and implementation and assessment tools.
The new version of ITIL® v3 released in 2008 has brought ITIL to a new era, driving ITSM to become a continuous improving process.
