PMI Agile Certified Practitioner (PMI-ACP) — Question 329

A newly formed development team experienced difficulty with accurately estimating product backlog items. As a result, the team failed to deliver all of the features in the sprint backlog for the past two iterations.
What should the team do to improve the accuracy of their estimates?

Answer options

• A. Decrease the sprint time box until the team is able to deliver the entire agreed-upon sprint backlog in a single sprint
• B. Discuss estimating techniques in the daily scrum meeting
• C. Increase the size of the development team until the team is able to deliver the entire agreed-upon sprint backlog in a single sprint
• D. Begin tracking estimated effort metrics as an input to performance evaluation

Correct answer: D

Explanation

The correct answer, D, suggests that by tracking estimated effort metrics, the team can analyze their estimation accuracy over time and improve their performance. Options A and C focus on changing team size or sprint duration, which do not directly address the estimation issue. Option B, while it promotes discussion, does not provide a systematic approach to improving estimation accuracy.
