I talk with managers all the time from large companies to small 3-5 person shops. Regardless of the size of the team, all managers want one thing. They want to know how to make their developers more productive. In my many years off working in IT as both a developer and a manager, I have come to the realization that there is one tool you can give a developer, regardless of the language they work in, that will make them more productive. Warning managers, you won’t like the answer.
