ITIL is a 5 volume set of practices that aligns IT services with business needs, and underpins the International Service Management Standard for IT service management. Each volume details a separate part of the ITSM lifecycle (ITSM meaning Information technology service management). ITIL isn’t applicable only specific to certain technologies or organizations, but instead provides guidelines that are fully adjustable to the users’ needs. ITIL certification can only be given to individuals, not organizations.
ITIL was originally published in the 1980s.
