What is ITIL?
ITIL = Information Technology Infrastructure Library. It’s a set of practices for IT service management (ITSM). ITIL outlines a systematic approach to ITSM that helps businesses improve relationships with their customers, be more cost-effective, manage risk, and develop a sturdy IT infrastructure that can handle change and growth.
ITIL helps companies align IT services with their business needs. As businesses became more dependent on technology, they needed a way to mesh their IT departments with the rest of the company. And while it originated in the UK, companies from all industries worldwide apply its practices.
Currently, the ITIL is made up of 5 books – each covering different processes and phases of the IT service lifecycle. ITIL has been revised many times over the years, with the most recent one being ITIL 4.
