ITIL is the basis of the worldwide standard for quality IT Service Management, ISO 20000 ITIL was developed by the public and private sectors and globally adopted. ITIL is in the public domain. “The IT Infrastructure Library® (ITIL) is the most widely accepted approach to IT service management in the world. ITIL is a cohesive best practice framework, drawn from the public and private sectors internationally. It describes the organization of IT resources to deliver business value, and documents processes, functions and roles in IT Service Management (ITSM).” Source: UK Office of Government Commerce

Process : 

Process A process is a structured set of activities designed to accomplish a specific objective. Create value for all stakeholders. Are closed-loop systems. Turn inputs into defined outputs. Are organized around objectives. Include all required roles, responsibilities, tools, and management controls. Once defined and documented, must be controlled to ensure repeatable results.

Function : 

Function A function is a team or group of people and the tools they use to perform one or more processes or activities. Provide structure and stability to organizations. Are self-contained units of organizations, with their own capabilities and resources. Rely on processes for cross-functional coordination and control. Have their own knowledge base, built from experience. Can result in functional silos if there is an inward focus or lack of coordination

Role : 

Role A role is the set of responsibilities, activities and authorities defined in a process and assigned to a person or team. An individual can assume various roles over the course of the day Some times roles will be full time responsibilities

The History of ITIL : 

The History of ITIL 1980’s British government determined that the level of IT service quality they received was not sufficient. The Central Computer and Telecommunications Agency (CCTA) was assigned to develop a framework for efficient and financially responsible use of IT resources. This was a joint effort between the government and private sector experts. 2000 The CCTA merged into the Office for Government Commerce (OGC). Microsoft used ITIL as the basis to develop the Microsoft Operations Framework (MOF). 2001 Version 2 of ITIL is released. The Service Support and Service Delivery books were redeveloped. 2007 Version 3 of ITIL is released which adopts a lifecycle approach to Service Management with a better emphasis on IT-Business integration
