The correct answer is D – Reestimate all stories including values for A, B, and C. Agile promotes empirical process control, meaning teams adapt based on what they learn. When significant deviations are found in actual effort vs. story point estimates, the team should revisit and refine their estimation process, including reestimating stories to better align with reality.

From the PMI Agile Practice Guide:

“Estimates are revisited based on experience. Teams inspect and adapt during retrospectives, using data to improve future estimation accuracy.”

(PMI Agile Practice Guide, Section 5.3 – Estimation and Planning)

Mike Griffiths writes:

“When estimates prove inaccurate, teams should reestimate affected stories. Estimating is a collaborative process, and learning from past deviations is a key part of adaptive planning.”

(Mike Griffiths, PMI-ACP Exam Prep, Chapter 5 – Adaptive Planning)

Incorrect options:

A may distort estimation by comparison and not correct the root issue.

B manipulates velocity data and violates agile principles of transparency.

C attempts to “force fit” effort rather than inspect and adapt.

Answer: D

The purpose of the daily standup (or daily coordination meeting) is to help the development team stay aligned with the sprint goal and actively manage any risks or impediments that may be blocking progress. It allows the team to quickly discuss their progress, share potential issues, and identify dependencies that could affect the sprint's success. The focus is on team collaboration and ensuring that everyone is on track.

When issuesrecur across multiple iterations, it’s a strong indication that theroot cause has not been addressed. ThePMI Agile Practice Guide (Section 5.6 Retrospectives)andMike Griffiths’ PMI-ACP Exam Prep Book (Chapter 7: Continuous Improvement)recommend performingroot cause analysistechniques (e.g., 5 Whys, Fishbone diagram) to ensure that the true source of recurring problems is uncovered and resolved.

Option Bis correct: identifying root causes is essential to sustainable improvements.

Option Amay help but doesn’t address the underlying team-level process.

Option Cis usefulaftera solution is implemented but not the priority when the cause is unknown.

Option Dis helpful for tracking, but again, ineffective if the root cause is unidentified.
