During a sprint retrospective, the team identifies that communication breakdowns are causing delays. They propose a new collaboration tool. The project manager supports the idea but it requires additional budget. What should the PM do FIRST?
Proper evaluation and change control ensure the expenditure is justified and approved.
Why this answer
Option B is correct because the project manager must first evaluate the cost and benefits of the proposed collaboration tool to build a business case, then submit a formal change request to the change control board (CCB) for approval. This aligns with the PMBOK Guide's integrated change control process, ensuring that budget adjustments are justified and authorized before any expenditure.
Exam trap
The trap here is that candidates confuse the contingency reserve (for known risks) with the management reserve (for unknown work), or assume the project manager can authorize budget changes without formal approval, leading them to pick A or D instead of following the proper change control process.
How to eliminate wrong answers
Option A is wrong because using management reserve without approval bypasses the formal change control process and violates the principle that management reserve is controlled by management, not the project manager, and requires a change request for release. Option C is wrong because it dismisses the team's identified improvement without analysis, ignoring the retrospective's purpose of continuous improvement and the need to address communication breakdowns. Option D is wrong because contingency reserve is designated for known risks (e.g., identified in the risk register), not for an unplanned improvement like a new tool; using it for this purpose would be a misuse of funds and requires a change request.
