What is a benefits management approach used to assess?

The Benefits Management Approach in PRINCE2 is a document that describes how and when a measurement of the achievement of the project's benefits, both during and after the project, can be made. It is used to assess the performance of the project's products once they are in operational use, ensuring that the project delivers the intended benefits as outlined in the Business Case.
