The field of organizational learning has developed dynamically but is not ready for closure. This article reviews the cultural contexts in which research on organizational learning has been conducted since the 1960s, and the intellectual traditions that underpin the field. It traces changes in the types of organizations studied and in the range of agents of organizational learning attended to by scholars. The processes and models that have shaped the discussion over the past decades, and changes in the tone or color of the way organizational learning has been treated are also highlighted. Trends in organizational practices are identified as well. On the basis of this broad stocktaking exercise, key challenges for future research on organizational learning and knowledge creation are outlined.
