Explanation
The project manager should schedule a meeting with the stakeholder to better understand their request because this is the best way to address the stakeholder's needs and expectations, and to avoid any misunderstandings or conflicts. The project manager should not assume that the stakeholder's request is reasonable or unreasonable, but rather seek to understand the rationale, the urgency, and the impact of the request on the project. The project manager should also consider the stakeholder's influence, interest, and power, and how they may affect the project outcomes. By scheduling a meeting with the stakeholder, the project manager can communicate effectively, negotiate mutually beneficial solutions, and manage the stakeholder's expectations. The project manager can also use this opportunity to review and update the stakeholder register, the stakeholder engagement plan, and the communications management plan, as needed. References:
