Explanation = According to the PMBOK Guide, 7th edition, the communications management plan is a component of the project management plan that describes how, when, and by whom information about the project will be shared, stored, and distributed1. It also defines the communication requirements and expectations of the project stakeholders, such as the level of detail, frequency, format, and confidentiality of the information2. Therefore, the project manager should review the communications management plan with the team members, to ensure that they are aware of and follow the agreed communication protocols and methods. This would help to address the issue of the team member who never speaks during meetings, but sends emails afterwards, which may indicate a preference or a challenge for a different communication mode. The project manager should also encourage the team member to share their valuable suggestions during the meetings, as this would enhance the team collaboration and performance3.
