In PRINCE2, the Team Manager is responsible for creating Checkpoint Reports. These reports provide the Project Manager with a summary of the progress within a Work Package, detailing performance against plan, and highlighting any issues that might affect the work. References: PRINCE2 Foundation official study materials.

The Project Manager should review the Highlight Report to report to the Project Board on the status of the project's issues. The Highlight Report provides a regular summary of the stage status, including progress against the plan and details about any issues or risks, making it the appropriate management product for communicating current issues to the Project Board.References: (PRINCE2 7 Foundation Handbook, AXELOS)
