Never use velocity to compare teams or pressure for more output. It is a planning tool, not a performance metric. Track it over time to improve your forecasting accuracy.
Strong answers cover: tracking velocity over time, using historical data for planning, understanding that velocity is a planning tool not a performance metric, accounting for team changes and holidays, and avoiding the trap of comparing velocity across teams. Best candidates discuss how they have improved predictability over several sprints.
Tests agile practice depth. Candidates who weaponise velocity as a performance metric misunderstand its purpose. Those who use it for sustainable planning and forecasting demonstrate mature agile practice.
