Outside of ITIL, other IT Service Management approaches and frameworks exist, including the Enterprise Computing Institute's library covering general issues of large scale IT management, including various Service Management subjects. After the initial publication, the number of books quickly grew within ITIL v1 to over 30 volumes. IT Service Management as a concept is related but not equivalent to ITIL which, in Version 2, contained a subsection specifically entitled IT Service Management (ITSM).
The Practitioner Exam is three-hour, and it has just been changed to an objective-testing multiple-choice exam with only the official Reference Manual allowed. Configuration management contains current, accurate, and comprehensive information about all components of the IT infrastructure. How Did ITIL Start ICT Operations may often work closely alongside Incident Management and the Service Desk, which are not-necessarily technical in order to provide an 'Operations Bridge'.
The OGC also doesn t claim that ITIL is a framework, designed as one coherent model. There are a variety of proprietary approaches available from IT service providers, consultants, and research firms.
The discipline is not concerned with the details of how to use a particular vendor's product, or necessarily with the technical details of the systems under management.
