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

Knowledge management focuses on capturing, storing, and sharing organizational knowledge and does not govern which infrastructure components are authorized for use.

Service portfolio management oversees the lifecycle of services within the service portfolio and does not control the authorization or tracking of individual configuration items.

SACM maintains the Configuration Management System (CMS) and Configuration Management Database (CMDB), which track all authorized configuration items. By integrating with change management, SACM verifies that only approved components are introduced or modified, preventing unauthorized CIs from entering the infrastructure.

Financial management for IT services handles budgeting, accounting, and charging for IT services, not the authorization or configuration tracking of infrastructure components.
