Service Lifecycle
ITIL® Service Lifecycle Model

The architecture of the ITIL® manuals is based on the service lifecycle. “Service Strategy” defines the axis around which the lifecycle turns. The policies and objectives which are implemented through service design, service transition and service operation from the planning, to change and through to the operation as gradual phases. The continual service improvement reflects the continuous learning and improving and helps to position and prioritize improvement programs and projects on the basis of the strategic goals.
To enable the lifecycle to influence the activities in a customer and business oriented manner it is very important to organize the various information. Without an adequate structure the valuable knowledge is merely a collection of observations and practices – or even worse, it could give rise to competing objectives. The service lifecycle forms an organizational framework and determines the pattern of behavior to be adhered to. As a model for the delivery of sustainable, good services it amplifies the service management approach and helps provide a better understanding of its structures and connections.
