The correct answer isC – Initiate an estimation sessionbecause agile planning isiterative and collaborative. When delivery timing is in question, especially during a release planning session, the team must firstestimatethe size of the work (epics and user stories). Once estimates are made (often using story points or relative sizing techniques), velocity can be used to forecast delivery timelines.
From thePMI Agile Practice Guide:
“Estimation is typically performed at the beginning of a release or iteration planning session to determine how much work can be completed. Teams use estimation to size items and then apply their known or projected velocity to forecast completion.”
(PMI Agile Practice Guide, Section 5.3 – Estimation and Velocity)
Mike Griffiths’ PMI-ACP Exam Prep Bookalso states:
“Before making any delivery commitments, teams should first engage in collaborative estimation to understand the scope and effort of the work. These estimates then inform velocity-based forecasting.”
(Mike Griffiths, Chapter 5 – Adaptive Planning)
Why the other options are incorrect:
A– Scrum Masters do not estimate work; estimation is a team activity.
B– You cannot determine deliverables based on velocity until the work has been estimated.
D– Historical data can support forecasting but must be preceded by proper estimation of current backlog items.
Answer: C
