As an agile coach, one of my favorite expressions in response to nearly any situation I encounter in an agile team is—“trust the team” or “trust the process”. So here are a few examples of what I mean:

If you think the team has underestimated their work and are leaving velocity on the table, “trust the team”…

- If they have underestimated they can always pull in more work. And you know, you could be wrong, so allow the team to sort through how they understand, size, and execute their work. They’ll appreciate the trust you’ve given them and will invest in doing good work.

- If you do see poor estimation or poor execution & adjustment, then bring this to the attention of the team within their retrospective. Give them examples, but allow them to explore the most effective way(s) to improve.
