When a stakeholder expresses concerns about the project not delivering the expected business value, it is important for the project manager to review the business benefits realization plan. This plan outlines the activities necessary for achieving the planned benefits and identifies the timeline, tools, and resources required to ensure these benefits are fully realized over time. It also includes metrics and procedures to measure progress against benefits, roles and responsibilities, and processes for determining the extent to which each project benefit is achieved prior to formal closure. By reviewing this plan with the stakeholders, the project manager can address concerns by showing how the benefits are expected to be realized and making any necessary adjustments to ensure those benefits are achieved.

The Professional in Business Analysis Reference Materials also support the review of the business benefits realization plan as a means to ensure that benefits are derived from project outputs and are sustainable after project completion34.
