I speak with Michael about the M word. Yes Metrics and Agile teams have seemed to be at odds for a long time. If you look at a large enough population of teams using many differing methods you can however glean information that is useful. It turns out that on average Agile teams deliver on our goal of delivering higher quality software, predictably and without increasing costs. There is a lot the data does not say about individual teams but this information is gold when approached by one of the remaining skeptics.
I hope you enjoy this podcast.
