Continue reading this post and get to know more about history and basic principles of ITIL.
How ITIL came about
ITILoriginated from a government initiative. In the 1980s, the British government intensified its computerization program, leading to decentralization of the IT sector, converting many of its entities into global organizations. With this came the need to organize document consolidating best practices to assist in the process of change. Initially, the focus was aimed at British government agencies; however, ITILwas soon incorporated into the private sector, becoming a benchmark in many technology companies. The set of guidelines proposed by ITILcontinues to be a reference in organizations, even with the emergence of new methodologies for technology management, in a corporate environment.
Prior to the formalization of best practices, public agencies and companies adopted their own methodologies for the management of technology services. The lack of standard in the development of activities resulted in increased costs and the creation of unnecessary complexity for the consolidation of the IT sector in organizations.
ITIL timeline (milestones)
1986:CCTA (UK Government Central Computer and Telecommunications Agency) authorized the development of a common set of guidelines with the aim of increasing the efficiency of British government IT services.
1989:First books addressing ITIL are published, covering topics like Service Level, Management, Help desk (incorporating basic concepts of incident management), Contingency Plan and Change Management.
2000and 2001:Publication of ITIL V2 (Service Support/Service Delivery) and formalization of BS 15000:2000 standard, Specifications for IT service management, together with the code of best practices DISC PD 0005.
2007:Launch of ITIL V3, providing vision of the complete service life cycle, broadening the IT and support components needed to provide the services.
2011 Update:The version counts on five books addressing items like Service Strategy, Service Design, Service Transition, Service Operation and Continual Service Improvement. ITIL2011 is an update of the model (framework) that addresses significant additional guidance with the definition of formal processes that were previously implicated, but not identified, as well as the correction of errors and inconsistencies.
