Author and academic John Kotter has significantly advanced our thinking around team effectiveness, and he has taken it to a new level when he talks about the fundamental difference between teamwork and team performance. He suggests we often settle for the former when we really want the latter. Kotter argues that, all models and theories aside, for leadership teams to perform effectively in the organizational context, they need to do some “real” work together as a team. In other words, they can only learn to perform and trust each other when they are faced with genuine work to do. Performance and trust are outcomes, not inputs, and they are only achieved through actual work.
