Official Introduction to ITIL Service Lifecycle

This is the official gateway to ITIL®. It explains the basic concept of IT Service Management and the place of ITIL, introducing the new lifecycle model. It puts into context all the familiar ITIL processes from the earlier books and serves to illuminate the background of the new ITIL structure.

It describes why the service lifecycle approach is best practice in today's service management and makes a persuasive case for change. After showing high level process models it takes the reader through the main principles that govern the new version: lifecycle stages, governance and decision making and then the principles behind design & deployment and operation & optimisation.

The main body of the book introduces the five main titles with an introduction and clearly laid out summary of objectives, practice, key elements, roles and responsibilities and service performance. It then gives an overview of the guidance specific to each stage of the lifecycle.

Each chapter concludes with key messages and lessons, showing how the introduction relates to the full library with its deeper levels of practice expertise and structured application.
