Which process works with change management to ensure only authorized components are used?

Knowledge Management is responsible for capturing, storing, and sharing knowledge and information across the organization, and does not control or authorize configuration components.

Service Portfolio Management governs decisions about which services to offer and their lifecycle, not the authorization and tracking of individual configuration items.

SACM maintains the Configuration Management Database (CMDB), which holds records of all authorized configuration items (CIs) and their relationships. It integrates directly with Change Management to verify that components introduced or modified through a change are properly authorized, identified, and accurately reflected in the CMDB before use.

Financial Management for IT Services addresses budgeting, accounting, and cost recovery for IT services, and has no responsibility for component authorization or configuration control.
