The Project Management Professional (PMP) emphasizes the importance of direct communication with project stakeholders to ensure clear and effective information exchange. When a stakeholder is not attending meetings and is seeking information through a family member on the team, it is essential for the project manager to engage directly with the stakeholder to establish proper communication channels. This aligns with the principles of stakeholder engagement and communication management, which are critical for project success. The project manager should request a meeting with the stakeholder to discuss project updates and expectations, and to integrate the stakeholder into the communication management plan.
