Reiter-Palmon, Herman, and Yammarino (this volume) put forward a series of useful propositions about the nature of team creativity, its connection with individual creativity and cognitive processes, and its antecedents. This commentary highlights some issues raised by these propositions, and explores the emergence of team creativity in greater depth. In particular, it discusses existing principles of multi-level theory and measurement, and considers how they might be applied to team creativity. We conclude that there is no single unified way to treat the concept of team creativity, but just as the antecedents of creativity may change in different situations, so may the way in which the construct is defined.
