Explanation
The communications management plan is a component of the project management plan that describes how the project information will be communicated to the stakeholders, including thefrequency, format, content, and methods of communication1. The project manager should review the communications management plan and verify whether the stakeholder's needs are captured in the project management plan, and if not, update the plan accordingly. This will help to ensure that the stakeholder receives the appropriate information at the right time and in the right way. Requesting the project team to include the stakeholder's details and share the project status reports (A) may not be sufficient or effective, as the stakeholder may have different communication preferences or expectations. Scheduling a meeting with the stakeholder and including the stakeholder's needs in the project management plan (B) may be a good action to take, but not the first one. The project manager should first review the existing communications management plan and identify any gaps or issues before engaging with the stakeholder. Reviewing the stakeholder management plan and updating the stakeholder register may not be relevant or necessary, as the stakeholder is already identified and engaged in the project. The stakeholder management plan describes how the project manager will manage the stakeholder expectations and influence, not how the project information will be communicated to them2. References: 1:
