Service Design
The Service Design book provides guidance upon the production/maintenance of information technology policies, architectures, and documents.

Service Transition
The Service Transition book focuses upon change management role and release practices, providing guidance and process activities for the transition of services into the business environment.

Service Operation
This book focuses upon delivery and control process activities based on a selection of service support and service delivery control points.

Continual Service Improvement
This book focuses upon the process elements involved in identifying and introducing service management improvements, as well as issues surrounding service retirement.



ITIL Version 2

The previous version of ITIL focused less on lifecycle, and more on process. It was organized into a series of eight sets, which themselves were divided into two main areas: service support and service delivery.

Service Support comprised those disciplines that enable IT Services to be provided effectively. These are boradly concerned with delivering and supporting IT services that are appropriate to the business requirements of the organisation.

Service Support is divided into:

• Change Management
• Release Management
• Problem Management
• Incident Management
• Configuration Managment
• Service Desk
