A benefits management plan is a document that describes how and when the benefits of the project will be delivered, and how they will be measured and evaluated. It also aligns the benefits with the organization’s strategic objectives and shows how the project contributes to them. A benefits management plan can help the project manager communicate the value and benefits of the project to the stakeholders, especially if the project is in danger of failing or losing support. A benefits management plan is an output of the Identify Stakeholders process in the PMBOK Guide, and it is also covered in the PMI-PBA Exam Content Outline under Domain II: Needs Assessment. References:
