Functions and Processes in Service Transition
Transition Planning and SupportThe goals for transition planning and support include:
The objectives for transition planning and support include:
Change ManagementChanges have a proactive or reactive reason. Examples of a proactive reason are cost reduction or service improvement. Examples of reactive changes are solving service disruptions or adapting the service to a changing environment.Changes must be controlled adequately, so that:
Service Asset and Configuration ManagementThe purpose of Service Asset and Configuration Management (SACM) is to provide a logical model of the IT infrastructure. In this model the IT services are related to the different IT components needed to supply these services.SACM increases the visibility and performance of the service, release or environment.

Service Validation and TestingTesting of services is an important contribution to the quality of IT service provision. Testing ensures that new (or changed) services are 'fit for purpose' and 'fit for use'. 'Fit for purpose' means that the service does what the client expects of it, so that the service supports the business. 'Fit for use' addresses such aspects as availability, continuity, capacity and security of the service.The goal of service validation and testing is to provide a service that adds value to the client's business. Service interruptions may be damaging to business operations of service provider and clients who are recipients of the services. They may result in damage to reputations, financial loss and even (fatal) accidents. Imagine, for example, the role of IT in hospitals, the automotive or aerospace industries. EvaluationITIL defines the evaluation process as: A generic process intended to verify whether the performance of 'something' is acceptable, whether it has the right price/quality ratio, etc. or whether it is used, whether it is paid for, etc.Evaluation delivers an important piece of input for CSI and the future improvement of service development and change management. Knowledge ManagementThe goal of knowledge management is to improve the quality of the (management's) decision-making process by ensuring that reliable and secure information is available during the Service Lifecycle.Knowledge management is particularly relevant during Service Transition, as a successful Transition depends to a large extent on the information and knowledge of users, the service desk, support and the supplier. Specific examples of the application of knowledge management during Service Transition are:
