After my second retrospective on a new project, I unloaded some pretty harsh criticism about what we were building. I felt it was a “solution in search of a problem” and “not high value.” After proposing an alternative and convincing everyone to change direction, our sort-of Product Owner blasted me for not bringing my issues up sooner and basically wasting two weeks of work. I said I had voiced my concerns, but not strongly or formally, because I was focused on getting the sprint work done. My feeling was that it wasn’t constructive to second-guess things in the middle of a sprint, and that I trusted the people who made the decisions. Especially as the new guy on the team, I leaned towards agreement.
We both had a point. As a senior person, I had a responsibility to speak up. As a team members, I had a responsibility to get our work done. I don’t know if I made the right choice in this instance. Perhaps if I argued too loud too early, I wouldn’t have had enough credence for people to believe me, and would have been in a worse spot at the end. Or perhaps I would have saved two weeks or work.
This is one more reason I prefer one-week iterations. A week is too small to break up, so you just go heads down. But you don’t work on the wrong thing for too long. You get two or three times the chances to learn and improve.
