ITIL 4 PDF



ITIL overview

ITIL is a framework that provides guidance on all aspects of end-to-end service management. It covers the full spectrum of people, processes, products and partner usage. See details here on Axelos ITIL website https://itil.press to download ITIL 4 PDF book.

Today, ITIL is practiced by almost all companies that provide IT services to their customers.

The processes, tasks, and checklists described in ITIL are not specific to an organization, but can be implemented by any organization. This gives the organization a framework for planning, implementing and measuring IT services.

ITIL was published in 1989 by Her Majesty’s Office (HMSO) in the UK on behalf of the Central Communications and Telecommunications Agency (CCTA), which is now part of the Office of Government Trade (OGC).
