Adapted from "The Coaching Effect"
Why is it that a team can underachieve and then bring in a new manager and achieve significant growth? They altered the input that has the most powerful impact on performance outcomes—the manager. Yet in business, nobody quantifies coaching effectiveness. Executive leaders have forever been viewing incomplete or inaccurate data regarding team performance because they are not looking at the root cause of performance growth — the manager. This is the business version of Moneyball if you've ever seen the movie.
