I’m going to start off by saying that I know Scrum and metrics don’t necessarily get along. But I will also acknowledge that it’s a necessary evil in most cases. And in a lot of cases it doesn’t have to be evil. Metrics are simply: a method of measuring something. In Scrum, we measure a lot of things. We measure the size of our work items, we measure the effort or time it takes to complete them. We measure our accuracy. All of this is in our quest to become predictable as a team and to improve (and we need to start with a baseline measurement to know if we’ve improved). But when others start taking notice of our metrics, that’s when things get tricky.
I’ve been blogging a lot about commitment and estimating lately both on this blog and my work blog. In a discussion with a Product Owner the other day, we were talking about looking at story sizes after the sprint to determine if they were sized correctly. I think this is a great idea and I’d like to plan it into a retrospective.
