The 3rd version of ITIL was first issued in May 2007 and is known as the ITIL V3 or 2007 edition. It consists of 26 processes and functions which are grouped into 5 volumes. They are based on the concept of service lifecycle structure. The latest edition of the V3 is the ITIL 2011 edition.
The framework of ITIL V3 is divided into 5 sections:
Each organization needs to have a clear set of objectives and a proper well-planned business strategy in order to be successful. The business strategy of an organization explains how they intend to achieve their objective over time. Each unit of the organization needs to have a set of its own strategies and IT strategy is one among them. This IT strategy is defined by the Business Strategy and in turn, the IT Strategy provides support and validation for the Business Strategy. ITIL Service Strategy focuses on the concepts which can be used by the IT Service Provider to build their service strategy.
The services of an organization should be designed keeping the business objectives in mind. The stage in the lifecycle of the service which converts the service strategy into a plan to deliver the business objectives is service design. ITIL Service Design provides the necessary guidance for the design and development of services and service management practices.
The role of ITIL Service Transition is to move services and service changes into operational use. ITIL Service Transition also introduces the service knowledge management system (SKMS) which has the ability to support organizational learning and assist in increasing the effectiveness and efficiency of all stages of the service lifecycle. This provides benefits to people with the knowledge and experience of others, helps to support decision-making and improve the management of services.
The main objective of IT service operations is to ensure that the required IT services are delivered efficiently and effectively as per the service level agreements to the business users and customers. Service operations are vital for an organization as meticulously designed and implemented process will be rendered ineffectual if the operations are ineffectively conducted. IT Service Operation also helps to improve the service as periodic activities for performance monitoring, assessment metrics and data gathering are systematically conducted.
Continual Service Improvement is a type of process which utilizes techniques from quality management in order to learn from prior successes and failures and aims to constantly increase the efficiency and effectiveness of IT services and processes.
