When is it confirmed if a project's objectives have been achieved?

In PRINCE2, the Closing a Project process includes a specific objective to confirm that all project objectives have been achieved and that the project products have been accepted by the customer. This process formally wraps up the project by reconciling actual outcomes against the planned objectives documented in the Project Initiation Documentation. It is the designated process for confirming whether the project delivered what was originally intended.

The final end stage assessment (part of Managing a Stage Boundary) reviews progress at the end of a stage but does not confirm that all project-level objectives have been fully and finally achieved.

The Controlling a Stage process monitors and controls work within a single stage, focusing on day-to-day progress and exception handling rather than confirming final achievement of project objectives.

The Managing Product Delivery process governs the creation and delivery of individual products by specialist teams, not the confirmation of overall project objectives against the Business Case.
