“We equipped all the members of those teams with electronic badges that collected data on their individual communication behaviour—tone of voice, body language, whom they talked to and how much, and more. With remarkable consistency, the data confirmed that communication indeed plays a critical role in building successful teams. In fact, we’ve found patterns of communication to be the most important predictor of a team’s success. Not only that, but they are as significant as all the other factors—individual intelligence, personality, skill, and the substance of discussions—combined.”
