A small percentage of teams perform exceptionally well and have fun while doing it. And the secret to their success isn’t innate talent. It’s the way they work together. Ron Friedman, psychologist and the founder of Superteams, Inc., has studied the data on these high-performing groups across industries and identified the key leadership behaviors that drive sustained outperformance–from asking questions people often avoid to creating continuous feedback loops. Friedman is the author of the HBR article “How to Build a Superteam That Keeps Getting Better,” and the book Superteams: The Science and Secrets of High-Performing Teams.
