What can an agile practitioner conclude about team A and team B ' s estimates?

When comparing total scope (story points) and velocity, you can calculate the number of sprints each team expects:

Team A: 420 / 30 = 14 sprints

Team B: 280 / 20 = 14 sprints

Even though the story points are different, both teams estimate the same number of sprints, which means they estimate similar effort and duration relative to their own internal baselines. This aligns with the concept that story points are relative and not comparable across teams.

PMI Agile Practice Guide (Section 5.4: Velocity and Relative Estimation) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning) explain that velocity is a team-specific measure and cannot be directly compared between teams.

Option D is correct: both teams have estimated the same project size in their own context.

Options A and B incorrectly compare velocity between teams.

Option C is irrelevant; velocity is based on team experience, not technology assumptions.
