Time-driven controls in PRINCE2 are mechanisms that take place at predetermined intervals, such as end stage assessments or regular progress meetings, to ensure ongoing monitoring of the project's progression through its stages and the work being completed in work packages. They help in keeping the project on track by providing timely information on performance. References: PRINCE2 7 Foundation Handbook and official training materials.

The Project Board must review the Project Brief to confirm there is enough information to initiate the project.
The Project Brief includes the outline Business Case, the project's objectives, and how the project fits into the organization's objectives. This document is essential for the Project Board to understand what the project is intended to achieve, ensuring alignment with organizational goals and confirming that the project remains viable before moving forward into the initiation stage.
