Before responding to the concern, the project manager should review the stakeholder engagement plan to confirm whether this key stakeholder was properly consulted and involved. This step ensures that engagement strategies are aligned with project objectives and that no stakeholder was missed in the planning phase.
The PMBOK Guide - Seventh Edition emphasizes the importance of identifying, analyzing, and engaging all stakeholders appropriately, especially in sensitive public sector projects.
Option B is dismissive and can escalate conflict.
Option C assumes prior engagement without confirmation.
Option D is premature without validating the engagement process.

When a project is experiencing delays due to identified risks, the project manager should revise the project schedule and inform the stakeholders regarding any delays1. This approach ensures transparency and allows stakeholders to adjust their expectations accordingly. It's also important to analyze the scope that is at risk and divide it into smaller, tangible parts. Setting a very short daily meeting or call with the key leaders of the delivery team to closely monitor progress can also help manage the project schedule effectively1.

The project manager should follow the Monitor and Control Project Work process, which involves tracking, reviewing, and reporting the progress and performance of the project, as well as managing changes and issues that arise. One of the main outputs of this process is the work performance reports, which provide information on the project status, progress, forecasts, issues, risks, and corrective actions. The project manager should use these reports to communicate with the relevant stakeholders and manage their expectations regarding the impact of the component delay on the project schedule. The project manager should also assess the component delay and determine the appropriate response strategy, such as requesting a change, implementing a contingency plan, or escalating the issue to senior management. The project manager should not perform a detailed analysis of the release content for each component of the solution (B), as this is not relevant to the current issue and may waste time and resources. The project manager should not propose a new design of the solution to replace the external component with an internal one , as this may introduce new risks, costs, and scope changes that may not be feasible or acceptable to the stakeholders. The project manager should not ask for expedited delivery of the component to mitigate the risk of schedule delays (D), as this may not be possible or realistic, and may also increase the cost and quality risks of the project.

The change management plan is a document that describes how changes to the project will be managed, monitored, and controlled12. It defines the roles and responsibilities of the change control board, the change request process, the criteria for approving or rejecting changes, the impact analysis, and the communication plan for changes34. The change management plan is part of the project management plan, which is the primary source of information for how the project is planned, executed, monitored, controlled, and closed.
The project manager should refer to the change management plan first because it provides the guidelines and procedures for handling changes to the project scope, schedule, cost, quality, or any other aspect of the project. The project manager should follow the change request process to document the proposed change, assess its impact, and submit it to the change control board for approval or rejection. The change management plan also helps the project manager communicate the change to the relevant stakeholders and update the project baselines and plans accordingly.
The schedule management plan, the scope management plan, and the cost management plan are also important documents for managing the project, but they are not the first ones to refer to when a change is requested. These documents describe how the project schedule, scope, and cost will be planned, defined, monitored, controlled, and reported . They are used to establish the project baselines and measure the project performance against them. However, they do not provide the specific steps and criteria for dealing with changes to the project. The project manager should refer to these documents after the change request is approved, to update the project schedule, scope, and cost accordingly and ensure alignment with the project objectives and stakeholder expectations.
