Term Definition
service transition (ITIL Service Transition) A stage in the
lifecycle of a service. Service transition
ensures that new, modified or retired services
meet the expectations of the business as
documented in the service strategy and
service design stages of the lifecycle. Service
transition includes the following processes:
transition planning and support, change
management, service asset and configuration
management, release and deployment
management, service validation and testing,
change evaluation, and knowledge
management. Although these processes are
associated with service transition, most
processes have activities that take place
across multiple stages of the service
lifecycle. See also transition.
service validation and testing (ITIL Service Transition) The process
responsible for validation and testing of a
new or changed IT service. Service validation
and testing ensures that the IT service
matches its design specification and will meet
the needs of the business.

total cost of delivering an IT service, and the
total value to the business of that IT service.

supplier to meet the terms of its contract.

seven-step improvement process (ITIL Continual Service Improvement) The
process responsible for defining and
managing the steps needed to identify,
define, gather, process, analyse, present and
implement improvements. The performance
of the IT service provider is continually
measured by this process and improvements

infrastructure in order to increase efficiency,
effectiveness and cost effectiveness.

and managed in the CSI register.
