Here we will shortly discuss a framework that became a de facto standard in ITSM.
Everyone in the industry is getting certificates in ITIL, from people to SW. Why is that? Probably because ITIL is founded on best practices in IT since early 1980s
ITIL (Information Technology Infrastructure Library) is a best practices framework to manage IT services in an effective and efficient way.
ITIL was initiated in the second half of 1980’s by the British government in order to design a set of operational IT guidance. The main goal was to increase efficiency in Government IT and the task was given to Central Computer and Telecommunications Agency (CCTA).
Authors consolidated best practices and guidelines from existing industry standards in a so called Government Infrastructure Management Method (GITMM). In 1989 it was renamed to Information Technology Infrastructure Library (ITIL®).
During the 90’s it gained worldwide popularity as the most complete set of best practices in IT Governance.
The updated version 2 in the year 2000 gained even more followers in the IT industry, as it focused more on bringing IT and business to understand each other. It defined a standard for a common language in IT, especially around IT Service Management (ITSM ), which was covered by two central books: Service Support and Service Delivery.
ITIL® ITSM with its ten basic processes and Service Desk function covered basic needs of various IT service departments for best practice guidance in daily operations.

In the 2000’s two very important ITIL® offspring were created:
- MOF: Microsoft® Operations Framework is a complete and mature framework based on ITIL® V2, completely free of charge and public
- ISO/IEC 20000: ISO standard evolved from British standard BS15000 and provides ITIL® V2 related auditable set of requirements for IT service management business organizations willing to ensure full alignment with basic processes.

In 2001 CCTA became a part of the British Office of Government Commerce (OGC).
In May 2007 the third version of ITIL® was published. It introduced roughly 16 new processes and three functions. The main update was that processes were spread over five new lifecycle stages:
- Service Strategy
- Service Design
- Service Transition
- Service Operation
- Continual Service Improvement
