Teams have always spurred important feats of mankind. Major events in settings as varied as disaster response, healthcare delivery, and the creative arts reflect the culmination of years of innovative collaboration among innumerable teams. Equally poignant are the stories of team failure: a team of competent individuals who failed to gel - their conflicts and inability to collaborate setting the stage for disaster. Examples include the failure to anticipate terrorist attacks or the failure of healthcare teams to stanch the 2014 Ebola outbreak in West Africa. This talk leverages theoretical and methodological advances to decode the structural signatures of teams that explain how – and how well – individuals organize in teams and systems of teams.
