It is a procedure library that adopts a process-oriented approach created by bringing together the best practices and experiences that can be used for important information technology organizations. ITIL framework processes planning, linking organizations’ practices, activities, define approaches, tasks, processes and activities on which knowledge can be based; however, it does not explain how these activities should be implemented. ITIL seems to have a structure based on practice rather than theory, which is actually adopted as a standard in the world. It can be applied by IT groups of organizations in the production, service, public and IT sector.
Historical development of ITIL over the years
In the 1980s, the Central Computer and Telecommunications Authority developed a series of recommendations. ITIL started on the basis of the best practices that manage IT services.
In 1989-1996, the number of references increased to thirty volumes in ITIL version 1.
In the early 1990s, large companies and government agencies in Europe adopted this framework. As its use increased both in the UK and worldwide, IT has changed and evolved, and ITIL has improved.
CCTA joined OGC (Office of Government Commerce) in 2000, and the books published by OGC were shared with the whole world, so there were processes open to everyone. Microsoft essentially modeled and used ITIL to develop its proprietary Microsoft Operations Framework program. In addition to this topic, the world’s first ITIL compliant standard BS 15000 has been published.
With the redevelopment of Service Support and Service Delivery books, ITIL version 2 was released in 2001 as 8 books.
In 2002, the BS15000 service management standard was revised and regulated.
It was published in 2007 as 5 books used as the main source in ITIL version 3.
In 2018, Axelos announced ITIL 4 – a major overhaul to the entire framework and the biggest change since ITIL v3 was published in 2007. ITIL 4 offers a more agile, flexible and customizable version of ITIL that is updated for modern businesses. The latest version encourages less siloes, more collaboration, communication across the entire business and integrating agile and DevOps into ITSM strategies.
ITIL’s for an organization and businesses,
- Increased user and customer satisfaction with IT services.
- Improved service availability increased direct business earnings and revenue.
- Financial savings through reduced rework, wasted time, improved resource management and utilization.
- Improving marketing time for new products and services.

ITIL is a set of practices that imparts practical and strategic ITSM guidance. ITIL is used as a guide to help groups improve the value of their services by focusing on co-creating business value and solving business issues, rather than just improving IT capabilities. ITIL focuses on the most convenient service management, while ISO 27001 focuses on information security.
