In this article the authors explore a number of empirical studies which map factors which are important for teams to be efficient. This nice mapping is a good entry point for team leaders to understand what kind of potential they can expect from their teams and to read upon how to inspire that potential.
Very interesting article, but beware that it is not only about software development.
