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

Service level management defines, negotiates, and monitors SLAs with customers and has no responsibility for tracking infrastructure component relationships.

Change management governs the approval and controlled implementation of changes to the IT environment, not the recording or reporting of CI relationships.

Incident management focuses on restoring normal service operation after disruptions and does not map, control, or report on infrastructure component relationships.

SACM maintains the configuration management database (CMDB), which stores all configuration items (CIs) and the relationships between them across the IT infrastructure. It is explicitly responsible for controlling, recording, verifying, and reporting on the status and interdependencies of IT components throughout their lifecycle. No other ITIL process holds ownership of this infrastructure relationship mapping function.
