47. Based on the work breakdown structure (WBS) for a project with the requirement to lower a restaurant's food costs, preliminary work performance data indicate that the initial target has not been achieved. The project manager is reviewing suggestions to identify suitable actions for closing the gap. Once the desired scope change has been selected, the project manager will update the project plan.
Answer: C
The change in scope requires an update to the scope baseline, so the project manager should use the change control system to update the baselines for time and cost.
In this scenario, the project manager must make adjustments to reflect the new scope, which entails updating the scope baseline. Utilizing the change control system is essential for formally recognizing and managing these updates to ensure that all stakeholders are aligned with the revised project parameters.
A) The project plan needs to remain unchanged, so the project manager should reject the essential scope change to avoid incurring contractual penalties because of a delay.
This option is incorrect as rejecting the necessary scope change would not address the issue of the initial target not being achieved. Maintaining the status quo could lead to further complications, including failing to meet project objectives and potentially incurring greater costs in the long run.
B) The change in scope is funded in the contingency allowance, so the project manager should accept the variances in baselines for scope, time, and cost.
While accepting variances may seem practical if funded by contingencies, this option does not emphasize the need for formal updates to the baselines. Without a structured approach to change management, the project risks becoming misaligned with its established goals and stakeholder expectations.
C) The change in scope requires an update to the scope baseline, so the project manager should use the change control system to update the baselines for time and cost.
This option is correct because it acknowledges the necessity of updating the scope baseline in response to the identified gap in performance. Using the change control system ensures that all changes are documented and approved, maintaining clarity and accountability throughout the project.
D) The change in scope is funded in the budget for managerial reserves, so the project manager should draw upon the reserve to cover the variances in baselines for scope, time, and cost.
This choice is misleading as it focuses on budgetary aspects rather than the critical need to formally update the project baselines. While managerial reserves can provide financial flexibility, they do not replace the need for a structured change management process to ensure comprehensive project alignment.
Conclusion
The correct answer, C, emphasizes the importance of updating the scope baseline through a formal change control process, which is essential for effective project management. Other options either ignore the necessity of these updates or misinterpret the project's financial management aspects. Thus, only C provides a comprehensive solution that ensures the project remains on track to meet its objectives.
