Learning and development is a core part of evolution which by definition is a highly complex and slow phenomenon; perhaps the most complex of all. Consequently, organizational learning interrelated to the evolution of complex organizations on their own merit, could had been only studied by human beings if a specific focus or departure point existed; and not one but many did.
In 2011 we can count already fifty years of research on a huge variety of complementary issues related to organizational learning and an overwhelming amount of literature. In my opinion classification of approaches is no longer of use at the point reached. Instead, an inclusive review or a monograph that will make a first attempt to put all the pieces of the organizational learning puzzle in place would be highly valuable.
Systems Thinking is a term to indicate one of the approaches within the wide and diverse Organizational Learning approach. Systems Thinking indicates that the approach to Organizational Learning has as a starting point the Systems Dynamics science (MIT Sloan School of Management).
