When a new stakeholder is assigned to a project and expresses concerns about the benefits of the deliverables, it is important to address these concerns directly and proactively. The benefits realization plan is designed to outline the activities necessary for achieving the planned benefits, including a timeline, tools, resources, and metrics for measuring progress. Reviewing this plan with the stakeholder can help clarify how the deliverables will contribute to the project's benefits and align with the stakeholder's expectations. This approach is supported by the Benefits Realization Management Framework, which emphasizes the importance of engaging stakeholders in understanding and supporting the benefits realization process.
