Exam PMI-ACP topic 1 question 37 discussion

A& C already completed so useless to re- estame them again. A is the correct answer

A and B are similar stories, and not "same" stories. So although A & C are already completed, reviewing what went wrong during estimation(retrospective), and re-estimating all the stories would be the right approach.

A. Increased points for B: This assumes the error applies only to story A and B will be similar, which might not be true. Overestimation can lead to under-delivering in other areas. B. Add points to current iteration: This doesn't address the underlying reason for the discrepancy and doesn't improve future estimations. C. Assign more resources: Throwing resources at a potentially inaccurate estimate is inefficient and doesn't guarantee faster completion.

Option D Estimate Activity Durations: This process emphasizes the need to update estimates throughout the project based on actual performance data and align with continuous improvement.

D is the Correct Answer

Histórias concluídas não estimadas. Fico com A

Vote D

Confusing question. D seem more realistic. A - "Story A took much longer than story C" How much? Assign story B more than 8? How much? Meaning could assign: 12, 20, 40? So undefined option. D - Adaptation based on empiricism in practice, but Scrum Master cannot re-estimate, the team can do.

Option D. Re-estimate all stories including values for A, B and C. This aligns with the Agile principle of "Continuous improvement" and the Agile practice of "Adapt and adjust." After discovering that the initial estimates were inaccurate, the team should re-estimate all stories, including A, B, and C, to reflect the actual time required to complete them. This enables the team to adjust their planning and improve their estimation accuracy for future sprints. Additionally, the team can identify any issues that contributed to the inaccurate estimate for story A and take steps to address those issues to prevent similar problems in the future.

I vote for D. Re-estimate to re-establish baselines again

Changing my answer to A. I do not like the question; the agile manager has no authority to update the product backlog or the sprint backlog. Stories are estimated by the development team and the Agile coach is not the right person to update the story points. The question is asking about what the agile practitioner should do. Out of the given answers, A is more appropriate as there is no benefit in re-estimating completed stories from the previous sprint.

I am going with D. All other options talk about "Assigning". Scrum Master or an Agile Manager does not assign anything to agile teams. Agile teams are self-organizing and self-managing, he/she only facilitates discussion and coach agile best.

How can A be the correct answer, as it's assumed that A is underestimated. Yes A (3 points) took longer to complete than C (8 points), what if it's C being grossly overestimated? C could be 1 point in reality, and hence A at 3 points is still correct.

A is correct for me A similar to B , A took more time than C means B should be assigned more than 8 points

i vote A

I choose A

D is the Answer. Once estimated a story points can not be changed. If the task is found to be too big it can be broken down into smaller pieces but the points remain the same.
