What is ITIL? (Information Technology Infrastructure Library)
Introduction
What is ITIL?
The Information Technology Infrastructure Library (ITIL) is a widely accepted approach to IT service management (ITSM) that provides a set of best practices for delivering high-quality IT services. ITIL's framework is based on a comprehensive set of guidelines that focus on aligning IT services with the needs of businesses.
Originally, it was coined in the 1980's by the UK's Central Computer & Telecommunications Agency as recommendations to standardize IT practices. Now - it's more of an acronym to describe the practices itself.
