With my engineers, I set the expectation that to have a productive, free-flowing debate, we need to be able to sort comments and issues into in-scope and out-of-scope quickly and easily as a team. I call this technique “true but irrelevant,” because I can typically sort meeting information into three buckets: things that are true, things that are false, and things that are true but irrelevant. Irrelevant is just a punchier way of saying out of scope.
