ITIL

Also known as: Information Technology Infrastructure Library

framework · governance and compliance · regulatory-standard

Framework for IT service management including service strategy, design, transition, operation, and continual improvement.

ITIL is the dominant framework for IT service management (ITSM), providing process and practice guidance for delivering and supporting IT services. Originated by the UK Government's Central Computer and Telecommunications Agency (CCTA) in the late 1980s, it evolved through successive editions: v2 (2000-2001) consolidated the original 30+ books into a process-oriented set, v3 (2007, refreshed 2011) introduced the service lifecycle structure, and ITIL 4 (2019) substantially restructured around the Service Value System, four dimensions of service management, and 34 management practices spanning general, service, and technical domains. Stewardship moved from CCTA to OGC, then to the AXELOS joint venture in 2013, and to PeopleCert in 2021. The ITIL 4 emphasis on value co-creation, agile/DevOps integration, and outcomes over processes was an explicit response to criticism that v3 had become process-bureaucratic.

Designing, delivering, and improving IT service management at organizations of all sizes; common reference framework in IT operations and support functions; basis for ITSM tooling design.

Common criticisms

v3 process orientation widely criticized as bureaucratic and tool-driven
certification industry incentivizes credentialing over capability
framing of ITSM as a separate function challenged by DevOps and SRE
tension between process discipline and continuous-flow software delivery
PeopleCert commercial control over content and certification creates accessibility friction.
