What is ITIL?
In the 1980s, the UK’s Central Computer and Telecommunications Agency (CCTA) created ITIL to standardize IT service management. ITIL has since become a global framework, helping organizations improve efficiency, customer satisfaction, and service delivery through structured processes and roles.
The Evolution Of ITIL
ITIL Version 2
In the early 2000s, ITIL underwent a pivotal moment with the launch of Version 2. This release introduced ITIL Service Management Practices, a foundational framework for structured IT service management. Central to Version 2 were two key components: Service Support and Service Delivery, which outlined procedures and roles for managing IT services comprehensively. Emphasizing service availability, reliability, and quality, Version 2 laid the groundwork for subsequent iterations of the ITIL framework.
ITIL Version 3 (2007)
In 2007, ITIL Version 3 (ITIL v3), also known as the ITIL 2007 Edition, introduced a more comprehensive approach to IT service management. It featured a five-stage service lifecycle model: service strategy, service design, service transition, service operation, and continuous service improvement (CSI). This model expanded on the concepts of ITIL Version 2, emphasizing the integration of IT services with business objectives. ITIL v3 fostered a culture of innovation and improvement within IT departments, encouraging constant evolution to align with organizational goals.
ITIL 2011 Update
An updated IT Infrastructure Library (v3) version, called the ITIL 2011 Edition, was released in 2011. This revision clarified and improved upon prior instructions and procedures while resolving inconsistencies and ambiguities.
ITIL Version 4 (2019)
The most recent version of the framework, ITIL Version 4 (2019), differs significantly from its predecessors. In response to the changing digital world and the increasing value of agility, cooperation, and customer-centricity, ITIL 4 (released in 2019) brings a more contemporary and adaptable method to IT service management. The Service Value System (SVS) and the Four Dimensions model are two of ITIL 4’s most prominent features. The SVS offers an integrative perspective on IT service management, while the model highlights the significance of partners, processes, products, and people in providing value to customers. In addition, the ITIL Practitioner, a new concept introduced in ITIL 4, represents a skill set that goes beyond that of a conventional IT service manager.
