In the PRINCE2 framework, a type of issue that can commonly occur is a request for change. This refers to a proposal for a change or modification to any aspect of the project, which may involve changes to the project's baseline aspects such as scope, product descriptions, quality criteria, or timeframes.

When the Project Board instructs the Project Manager to implement a request for change, details of that change are contained in an Issue Report. This document provides a detailed description of the issue, its evaluation, and the decisions regarding its resolution, including any changes to be implemented. References:

The purpose of the 'Directing a Project' process in PRINCE2 is to enable the project board to be accountable for the project's success by making key decisions and exercising overall control while delegating the day-to- day management of the project to the project manager. This includes the authority to initiate and close the project, deliver stage boundaries, and be updated on project progress.

The Project Product Description in PRINCE2 is a document where the project manager records specific requirements that must be met for the user to accept the final product, including criteria for user satisfaction.
This document provides a detailed description of the purpose, composition, derivation, and quality criteria of the project's main deliverable or product.
