According to the PMBOK Guide, 7th edition, one of the key activities of the project manager is to engage stakeholders and manage their expectations throughout the project. This includes discussing the options with the client as part of the change control process, which is a formal and documented procedure that defines how changes to the project scope, schedule, cost, quality, or any other aspect of the project will be requested, evaluated, approved, rejected, or implemented. In this scenario, the client’s request to use a new workaround instead of the approved contingency plan is a change request that may affect the project objectives and outcomes. Therefore, the project manager should discuss the options with the client as part of the change control process, and evaluate the impact, feasibility, and benefits of the proposed workaround, as well as the implications of not following the contingency plan. Option D is the best answer for this question.
Option A is not the best answer because requesting to use the management reserve to keep the schedule is not the next thing that the project manager should do. It is a possible action that the project manager may take if the change request is approved and the project budget is insufficient to cover the additional costs of the workaround, but it is not a necessary or immediate action. Moreover, requesting to use the management reserve may not always be feasible or desirable, as it may increase the project costs and risks, and may require the approval of senior management or the project sponsor.
Option B is not the best answer because mitigating risks associated with the workaround to avoid project delays is not the next thing that the project manager should do. It is a possible action that the project manager may take if the change request is approved and the workaround introduces new or increased risks to the project, but it is not a proactive or effective action to resolve the current issue. Moreover, mitigating risks may not always be possible or sufficient, as some risks may be unavoidable or unpredictable, and may require other risk response strategies, such as avoidance, transfer, or acceptance.
Option C is not the best answer because proceeding with the approved risk response plan is not the next thing that the project manager should do. It is a possible action that the project manager may take if the change request is rejected and the contingency plan is still valid and applicable, but it is not a respectful or collaborative action to deal with the client’s request. Moreover, proceeding with the approved risk response plan may not always be appropriate or acceptable, as the client may have valid reasons or new information to suggest a different workaround, and may escalate the issue or withdraw their support if their request is ignored or dismissed.
