In my experience, teams can’t reliably improve what they don’t measure. And the process of agreeing on what to measure, and how, is really helpful for getting a more nuanced perspective on what it is you’re trying to achieve, and why. Besides, it’s a fact of life that teams need to manage expectations around delivery, and measuring flow or velocity are the simplest ways I am aware of to do that. YMMV.
Applied to our experience in making music: what ever it is we seek from making music, whether it is relaxation, or the satisfaction of releasing music that other people care about, it can’t hurt to write that down, and then measure if we actually get that out of it. Because should we find out that we don’t, that would be a very good reason for adapting our approach.
