The Change Management needs to be informed on the positive result of the testing and the data set status needs to be changed to waiting. ITIL version 3 views capacity management as comprising three sub-processes: business capacity management, service capacity management, and component capacity management (known as resource capacity management in ITIL version 2). Detailed definition of implementation instructions for the Capacity improvement. The Test is split up in two main test areas: If both testing areas (see above) are positive, the data set is set in status enabled. Services are monitored to gather data, which identify trends and indicate exceptional conditions. Within this activity the Capacity section of the service design package is defined.
