The risk response type "Transfer" is applicable to both threats and opportunities. This response involves transferring the ownership of the risk to a third party who is better able to manage the risk, thus applying to both positive and negative risks.

The Highlight Report in PRINCE2 is used by the Project Manager to review the performance of a Work Package against its cost tolerance, among other factors. This report provides the Project Board with a summary of the stage status, and is a key tool for monitoring overall project progress, including financial performance.

The statement that technical stages include the Managing a Stage Boundary process activities is false.
Technical stages refer specifically to the application of skills and techniques during the project delivery process. The Managing a Stage Boundary process is concerned with the end of a management stage and planning the next stage, not directly with technical delivery.

The project mandate should provide the terms of reference for the project. These define the purpose and objectives of the project, setting the foundation for further project definition and planning in subsequent processes.

The purpose of the 'closing a project' process in PRINCE2 is to verify that all project objectives have been delivered and that the project has nothing more to deliver. It ensures that all project products have been handed over and accepted, and evaluates the performance of the project against its baselines. References:
