The best teams I’ve worked with have shared one commonality. We had a strong opinion on what we are building – almost to an obnoxious level. A belief that what we are building is the correct solution for the problem. We knew what to do and how to do it, usually. And sure, when there was enough evidence to the contrary we course corrected and changed our opinions. But we always had an opinion.
Have you ever noticed that feedback is implicitly considered to be right, when it’s purely opinion? What someone thinks of something is their opinion. Feedback is rarely about facts, it’s about feel, which is great except when it’s taken as truth.
Conversely, I’ve worked on teams missing this opinionated approach. Where the team is stifled by indecision and relies on research or data to tell them their next move, no matter how small that may be. They can only react to what is in front of them and miss the capacity to interpret feedback that aligns with, or goes against the greater product direction. This is usually where good ideas go to die and the status quo wins out.
