According to the PMBOK Guide, the project manager should manage the project scope, including the planning, validation, and control of the scope. The project manager should also manage the project changes, including the initiation, evaluation, approval, and implementation of the changes. In this scenario, the project manager received a request to add additional changes 1 day before the planned change date. This is a potential change to the project scope that may also impact the project time, cost, quality, and other aspects. The best course of action is to review the additional changes and perform integrated change control. This can help the project manager to assess the feasibility and desirability of the change request, and to determine the appropriate response and approval. Reviewing the additional changes and performing integrated change control (option C) is the best solution to the issue, as it demonstrates proactive and effective project scope and change management. Rejecting the changes as the lead time is too short (option A) may not be feasible or ethical, as it may violate the customer’s expectations and satisfaction, and may damage the trust and relationship with the customer. Determining whether the project team is capable of making the changes (option B) may not be sufficient or realistic, as it may ignore or overlook the impact and value of the change request, and may create a conflict or resentment among the project team. Checking if the changes are covered in the statement of work (SOW) (option D) may not be relevant or helpful, as it may not address the change request itself, nor does it account for the possible deviations or changes that may occur during the project execution. References: : Project Management Institute.
