The correct answer is C — During the retrospective, discuss the issue and create an action plan to avoid it in the future.
When teams misestimate or experience incomplete work, it’s important to reflect during the retrospective and create action items. This is a fundamental aspect of agile: continuous inspection, adaptation, and team-driven improvement.
PMI Agile Practice Guide:
“Retrospectives help identify opportunities for improvement. The team reviews its estimation accuracy and adjusts processes or practices based on patterns observed.”
(PMI Agile Practice Guide, Section 5.8 — Retrospectives)
Mike Griffiths elaborates:
“Estimating complexity is an area for ongoing learning. Teams use retrospectives to improve their sizing, identify knowledge gaps, and refine their planning techniques.”
(PMI-ACP Exam Prep, Chapter 5 — Adaptive Planning)
Other options:
A unnecessarily involves a project manager (non-agile).
B assumes one-size-fits-all rules, which limits team agility.
D ignores the structured opportunity the retrospective provides for team learning.
