What process is responsible for managing the lifecycle of all catalog items?

The process that is responsible for managing the lifecycle of all catalog items is service catalog management. This process ensures that the service catalog is created, maintained, and updated effectively to reflect the services that an organization provides. Service catalog management involves defining service offerings, establishing service levels, maintaining accurate service information, and ensuring accessibility for users.

By managing the catalog items' lifecycle, this process ensures that all services are aligned with business needs and are delivered effectively. It encompasses not only the introduction of new services but also the ongoing management of existing services and the retirement of services that are no longer relevant or needed, ensuring a comprehensive approach to service management that supports the organization's goals.

Other processes mentioned, such as catalog item management or service portfolio management, may have overlapping roles but do not specifically encapsulate the complete lifecycle management of catalog items as thoroughly as service catalog management does.
