Change Control is a systematic approach that includes the various steps needed to process changes made to a product or system.

Change control is a structured, systematic approach for managing changes to a product or system—covering every step needed to plan, assess, approve, and implement updates.

Carrying out change control consistently is an essential part of change management. Its purpose is to prevent unnecessary changes, ensure that every change is documented, minimize service disruption, and use resources effectively. In IT environments—where updates and changes are routine—change control is a core component of change management.

Typically, the change control process follows a defined sequence of steps, starting with the submission of a change request. Common IT change requests include adding features to software applications, applying patches, and upgrading network equipment or systems.
