The correct answer is C – Amount of work that can be accomplished in an iteration. To create a release plan, an agile team uses its historical or estimated velocity—how much work the team can complete in a single iteration. This information helps forecast how many iterations will be needed to complete the prioritized work in the product backlog.
From the PMI Agile Practice Guide:
“Velocity is used to determine how many iterations are required to complete the release backlog. Release planning requires an understanding of how much work can be completed per iteration to forecast delivery timelines.”
(PMI Agile Practice Guide, Section 5.3 – Iteration Planning and Velocity)
Mike Griffiths adds:
“Teams use their average velocity—the amount of work completed per iteration—as the basis for release planning. This supports predictable and empirical planning.”
(Mike Griffiths, PMI-ACP Exam Prep, Chapter 5 – Adaptive Planning)
Incorrect options:
A focuses too narrowly on a single story, not the full release.
B focuses on individual capacity, which is contrary to agile’s emphasis on team output.
D is vague; capacity is better measured by iteration.
