Like with everything else this is provable with numbers. What this is really about is having at least the appropriate amount of social intelligence for people who are otherwise individually productive. That’s it: productive people who know when to engage.

The way to solve for that is force additional business ownership onto the developers. When there is increased liability and increased risk of failure the developers will know exactly the right amount of feedback to provide, especially to each other, because are operating conditions are dictated by velocity and code quality baselines.

I am saying this as a software manager of people.
