Which of the following combinations covers all the roles in Service Asset and Configuration Management?

This option includes Service Desk Manager, which is a Service Operation role responsible for managing the help desk function and has no defined accountability within SACM.

The Configuration Administrator/Librarian manages day-to-day CMS entries and CI records, the Configuration Manager owns and governs the SACM process end-to-end, and the Service Asset Manager is specifically accountable for the full lifecycle of service assets. These three roles collectively span all SACM accountabilities without introducing roles that belong to other ITIL processes.

This option includes Change Manager, who owns the Change Management process - a separate ITSM process - not a role defined within SACM.

This combination omits the Service Asset Manager, which is a defined and distinct SACM role responsible for asset tracking and financial management of service assets, making the set incomplete.
