I was at a conference not that long ago speaking and sharing on various agile topics. As often happens, a young man stopped me to ask a few questions after one of my presentations. We struck up a nice conversation that eventually slipped out into the hotel corridors.
We started talking about sprint dynamics within Scrum teams and I happened to mention that I usually coach teams towards declaring their sprints a success…or (pause for meaningful effect) …a failure. That we do this as part of the teams’ Sprint Review, with the Product Owner being the final determinant based on whether the team achieved their Sprint Goal(s).
