The Self in Teams Groups that range from two persons to many are a very big part of social life—in all its facets—and most organizations rely on teamwork: the justification is that teams are better at solving problems and learn more rapidly and with more effect than individuals (Serrat, 2009). This précis offers reflections on personal experiences of teamwork, noting what does not work. The précis identifies a meaningful common purpose as the single highest requirement for getting work done but underscores other key ingredients of practice. The précis also notes the importance of integrating team identity for team effectiveness. Olivier Serrat 09/09/2019
