The purpose of this article is to present a specific approach to the practice of action research "in complex organisations". Clearly, there are many approaches to the challenge of doing action research in organisations; approaches that are, and also must be, quite context dependent and specific. But my purpose is neither to give an overview nor a recommendation of how action research is or should be done in complex organisations by different schools of action researchers around the world. The approach I will present has grown through practical experience accumulated over many years with doing action research in many different Norwegian organisations with organisational change and development as the specific objective. I will limit myself to an outline of this Norwegian context, and to how I and others have worked specifically with "organisational learning" both practically and theoretically within or in relation to a broad Norwegian or Scandinavian approach to action research and organisation development represented by many individuals.
