The Information Technology Infrastructure Library (ITIL) is a set of detailed practices for IT activities such as IT service management (ITSM) and IT asset management (ITAM) that focus on aligning IT services with the needs of the business.[1]

ITIL describes processes, procedures, tasks, and checklists which are neither organization-specific nor technology-specific but can be applied by an organization toward strategy, delivering value, and maintaining a minimum level of competency. It allows the organization to establish a baseline from which it can plan, implement, and measure. It is used to demonstrate compliance and to measure improvement. There is no formal independent third-party compliance assessment available for ITIL compliance in an organization. Certification in ITIL is only available to individuals. Since 2021, ITIL has been owned by PeopleCert.[2]


Responding to growing dependence on IT, the UK Government's Central Computer and Telecommunications Agency (CCTA) in the 1980s developed a set of recommendations designed to standardize IT management practices across government functions, built around a process model-based view of controlling and managing operations often credited to W. Edwards Deming and his plan-do-check-act (PDCA) cycle.[3]

  • In 1989, ITIL was released. It grew to a series of 30 books that recommended and provided IT best practices that focused on and catered for client and business needs.
  • In 1993, the examination institute EXIN developed the first certification scheme for ITIL.[4]
  • In April 2001, the CCTA was merged into the Office of Government Commerce (OGC), an office of the UK Treasury.[5]
  • In 2001, ITIL version 2 was released.
  • In May 2007, ITIL version 3 was released (also known as the ITIL Refresh Project) consisting of 26 processes and functions, now grouped into only 5 volumes, arranged around the concept of Service lifecycle structure. ITIL Version 3 is now known as ITIL 2007 Edition.
  • In 2009, the OGC officially announced that ITIL Version 2 certification would be withdrawn and launched a major consultation as per how to proceed.[6]
  • In July 2011, ITIL 2011 was released.
  • In 2013, ITIL was acquired by AXELOS, a joint venture between Capita and the UK Cabinet Office.[7]
  • In February 2019, ITIL version 4 was released. The main changes were: to consider end-to-end Service Management from holistic and value-centric perspectives, to align with philosophies such as Agile, DevOps, and Lean, and to reduce the emphasis on IT Service Management in favor of general Service Management.[8][user-generated source?]
  • In 2009 and 2011, researchers investigated the benefits of the ITIL implementation.[9][10]
  • In June 2021, PeopleCert completed the acquisition of Axelos.
