This department usually reports to one of three infrastructure groups depending on the processes receiving the most emphasis. When change management or production acceptance is the key process, this group often reports to computer operations. In a traditional mainframe environment this department was called production support and could include batch scheduling, batch processing and output processing. When problem management is the key process this group usually reports to the customer services or Help Desk department. In a world-class infrastructure, all of the key processes are managed out of a single systems management group that reports directly to the head of the infrastructure. This arrangement gives systems management the visibility and executive support needed to emphasize integrated process management.
