Change request management

The change request management delivers the functionality to ...

  • define a change request,
  • monitor live change behavior during the time period of the change request(s) and
  • document the correct implementation of all planned changes after completion of the change period of the change request.

Based on Asset & Configuration Item Inventory.


A change request defines for which instances a change is planned at a time or series date. A change request period is created for each time or series date period of a change request. The complete documentation of a change request is documented in the change request period.
