A project manager leads a regulatory initiative with tight, non-negotiable timelines.

Before taking any action, the project manager should gather more context and engage the team to assess feasibility. This includes evaluating schedule impacts, resource constraints, regulatory implications, and whether scope trade-offs are required. This approach aligns with the PMBOK® Guide’s recommendation to evaluate change impacts before making decisions.

Option A is misaligned; root cause analysis is more appropriate for problem resolution, not for scope acceleration.

Option B assumes approval and feasibility without review.

Option C applies to Agile backlog reprioritization but this is a regulatory milestone, likely not in a product backlog.
