The ITIL (Information Technology Infrastructure Library) framework is a set of best practices and procedures for IT service management and IT asset management. It focuses on aligning IT services with the needs of the business, aiming to improve efficiency, achieve predictable service delivery, and reduce IT operations cost. ITIL provides guidance and best practices for managing IT services throughout their entire lifecycle, from planning and delivery to maintenance. It is designed to help organizations create predictable IT environments and deliver the best customer service possible by streamlining processes and identifying opportunities to improve efficiency. The framework is not a rigid checklist but rather a set of guidelines that can be adapted to an organizations unique requirements. ITIL has gone through several revisions, with the latest iteration, ITIL 4, maintaining a strong emphasis on fostering an agile and flexible IT department, with a renewed focus on customer experience and digital transformation.
