Toward the end of a project, the project manager did not receive approval from a key stakeholder because the necessary deliverables were not functioning as expected.What should the project manager do next?

This option focuses on how to engage stakeholders effectively throughout the project. While it is important for managing stakeholder relationships, it does not directly address the current issue of the deliverables not meeting expectations. Revisiting the engagement plan will not provide the necessary insights into the quality of the deliverables.

The quality management plan outlines the processes for ensuring project deliverables meet quality standards. Although it is relevant, it does not specifically trace the requirements back to their sources. The RTM is more suitable for identifying gaps between stakeholder needs and the actual deliverables.

The work breakdown structure is a tool used for project planning and tracking tasks. While it provides an overview of project deliverables and their breakdown, it does not directly assess whether the deliverables meet the stakeholders' requirements. Therefore, it may not help the project manager resolve the immediate issue concerning the deliverables' functionality.
