IT Service Management Architecture

ITIL gives a detailed description of a number of important IT practices with comprehensive checklists, tasks and procedures that can be tailored to any IT organization. The ITIL recommendations were developed in the 1980s by the UK Government's CCTA in response to the growing dependence on IT and a recognition that without standard practices, government agencies and private sector contracts were independently creating their own IT management practices and duplicating effort within their Information and Communications Technology (ICT) projects resulting in common mistakes and increased costs. On July 20, 2006, the OGC signed a contract with the APM Group to be its commercial partner for ITIL accreditation from January 1, 2007.

The plan involves identifying services critical to the business that require additional preventive measures.
