Despite the growing popularity of the term "organizational learning," writings on the topic have little consensus in terms of definition, perspective, conceptualization, and methodology. This paper examines the dichotomy between the 2 main streams of theorizing in the field. The first stream, prescriptive writings on the learning organization, is concerned with the question "How should an organization learn?" Targeting practitioners, these studies are usually based on the authors' consulting experience and seldom follow rigors research methodologies. They also tend to overgeneralize their theories to all types of organizations. Descriptive research on organizational learning falls into the 2nd stream which tackles the question "How does an organization learn?" These are academic studies striving for scientific rigor. Nevertheless, they often fail to generate useful implications of practitioners. Brief suggestions are made to integrate the 2 streams of research.
