In PRINCE2, the two time-driven controls are Highlight Reports and Checkpoint Reports. Highlight Reports provide regular updates to the project board on the status and progress of the project at pre-defined intervals. Checkpoint Reports are produced at a regular frequency and are used to inform the Project Manager about the progress of the work packages being completed. Both of these reports are time-driven, meaning they are created based on a specific schedule or time frame, rather than being event-driven.
