The correct answer is D – Use the team ' s historical velocity to calculate a range of features that can be delivered. Agile emphasizes forecasting over commitment, and this is achieved through empirical data such as velocity. Providing a range based on historical velocity allows for realistic planning while acknowledging uncertainty.
From the PMI Agile Practice Guide:
“Agile forecasting is based on empirical data. Teams use their past velocity to forecast how much work they can complete in a given time frame. This forecast is typically expressed as a range to account for variability.”
(PMI Agile Practice Guide, Section 5.3 – Adaptive Planning and Forecasting)
Mike Griffiths supports this:
“Rather than commit to fixed scope, agile teams use historical velocity and prioritized backlogs to forecast delivery. Forecasts are probabilistic, not promises.”
(Mike Griffiths, PMI-ACP Exam Prep, Chapter 5 – Estimation and Forecasting)
Incorrect options:
A violates agile’s core value of responding to change over following a fixed plan.
B delays valuable forecasting data.
C implies commitment rather than forecast.
