ITIL is the preeminent framework for managing IT service delivery around the world. ITIL 4 defines a Service Value System that prescribes specific practices and activities during the design, development, delivery, and support of IT services.
For the purposes of this discussion, IT services are any IT activities that deliver business value to a company's end users, customers and other internal or external stakeholders. Examples of IT services include centralized corporate email and corporate websites based on back-end IT processes, such as server and network administration.
By adopting the ITIL framework, companies ensure that their services are delivered according to a set of consistent, well-defined practices that incorporate best practices and processes, resulting in a predictable level of service for users.
The benefits of ITIL include reduced cost of service development and deployment, improved customer satisfaction with service delivery, increased productivity from IT personnel, quality improvements, better management metrics of services and increased flexibility in adapting services to changing business requirements.
