ITIL (Information Technology Infrastructure Library) is a set of best practices and guidelines for managing IT services to align them with the needs of businesses. It provides a structured framework for delivering high-quality IT services, focusing on processes such as incident management, service desk operations, and change management. ITIL helps organizations improve efficiency, reduce costs, and enhance customer satisfaction by standardizing IT processes and ensuring they support business goals. Widely adopted in IT service management (ITSM), ITIL promotes continuous service improvement and strategic alignment of IT with business objectives.
