n the knowledge economy, teams play a central role in decisions made within and across organisations. The reason why teams with diverse compositions are often used is arguably their ability to develop solutions that none of their members could have produced alone. Systems design, strategy and policy development, risk management, and innovation are just a few of the areas that call for team decisions. Unfortunately, a considerable number of behavioural research studies show that teamwork is fraught with difficulties. Teams often underestimate their fallibility, struggle with conflict, or are unable to share and integrate critical information effectively.
