ITIL

The Information Technology Infrastructure Library (ITIL) is a globally recognized framework for IT service management (ITSM). It offers practical guidelines to organizations on aligning their IT services and processes with their business goals. The ITIL framework comprises five core publications: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. Each publication covers a specific aspect of the IT service lifecycle.

Service Strategy focuses on planning and designing IT services to meet customer needs and expectations. It assists in defining value propositions and managing the service portfolio. Service Design provides guidance on designing efficient and cost-effective IT services, including service models, processes, and architectures. It also covers the creation of service level agreements (SLAs) to define service levels and costs.Service Transition concentrates on managing changes to IT services, including the control of service assets and configuration items. It also addresses testing and validation to ensure reliability and compliance with SLAs. Service Operation offers guidance for day-to-day IT service management, including incident and problem management, as well as service requests.
