Which process is responsible for controlling, recording and reporting on the relationships between components of the IT infrastructure?

Service Level Management is responsible for negotiating, agreeing, and reporting on service level agreements with customers; it does not control or maintain records of infrastructure component relationships.

Change Management governs the authorization and implementation of changes to IT services and infrastructure but does not maintain a record of the configuration items and their relationships.

Incident Management focuses on restoring normal service operation as quickly as possible following disruptions; it has no responsibility for controlling or recording infrastructure component relationships.

SACM is specifically designed to identify, control, record, report, audit, and verify service assets and configuration items, including all relationships between infrastructure components. It maintains the CMDB, which stores the complete inventory of CIs and their interdependencies, making it the sole process responsible for this function.
