ITIL

ITIL, which used to be called the Information Technology Infrastructure Library, is a set of guidelines for managing technology services in businesses. It helps companies make sure their computer and IT systems work well and meet the needs of their customers or employees.

ITIL provides best practices, like steps and checklists, that any company can use no matter what kind of technology they have. It helps organizations set a good standard and track how they are improving over time.

Unlike some other frameworks, ITIL does not have a way for whole companies to prove they follow its rules. Only people can get certified in ITIL, not the organizations themselves. Since 2021, the trademark for ITIL has been owned by a company called PeopleCert.

History

In the 1980s, the UK government made guidelines to help manage IT better. These ideas came from a famous thinker.

In 1989, ITIL started. It had 30 books with the best ways to handle IT for customers and businesses. Over time, ITIL changed and grew. In 2001, ITIL version 2 came out. In May 2007, ITIL version 3 was released, with ideas in five main areas. In July 2011, ITIL 2011 began. In February 2019, ITIL 4 started, focusing on service management and working with modern methods like Agile and DevOps. In January 2026, PeopleCert planned ITIL 5.
