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.
