A primary stakeholder cannot consistently attend status meetings. The project manager has been updating them informally and regularly, but the project manager is resigning and will not brief the incoming manager. How should the project manager ensure the new manager continues these updates?

The correct answer is to update the stakeholder engagement plan. This plan details strategies for engaging stakeholders based on their needs and impact. By documenting the specific informal communication approach for this primary stakeholder, the new project manager will have clear guidance to continue effective engagement. Updating the communications management plan is incorrect because while it defines how project information will be communicated, the engagement strategy for specific stakeholders, especially those with unique needs, belongs in the stakeholder engagement plan. Ensuring the project team has guidance is a good operational step but doesn't guarantee the new manager will be aware or that the guidance is formally documented. Updating project documents generally is too vague; the stakeholder engagement plan is the specific document for this purpose.
