ISO/IEC 20000 is the international standard for IT service management. It was developed in 2005 by ISO/IEC JTC1/SC7 and revised in 2011 and 2018.[1] It was originally based on the earlier BS 15000 that was developed by BSI Group.[2]
ISO/IEC 20000, like its BS 15000 predecessor, was originally developed to reflect best practice guidance contained within the ITIL framework,[citation needed] although it equally supports other IT service management frameworks and approaches including Microsoft Operations Framework and components of ISACA's COBIT framework. The differentiation between ISO/IEC 20000 and BS 15000 has been addressed by Jenny Dugmore.[3][4]
The standard was first published in December 2005. In June 2011, the ISO/IEC 20000-1:2005 was updated to ISO/IEC 20000-1:2011. In February 2012, ISO/IEC 20000-2:2005 was updated to ISO/IEC 20000-2:2012.
ISO 20000-1 has been revised by ISO/IEC JTC 1/SC 40 IT Service Management and IT Governance. The revision was released in July 2018. From that point certified entities enter a three-year transition period to update to the new version of ISO 20000-1, ISO/IEC 20000-1:2018 – Information technology — Service management — Part 1: Service management system requirements.
