“Mary Parker Follett was a prominent business philosopher of the period, who agreed with Sheldon about the need to emphasize human factors in management, but placing greater stress on the need to develop a science of cooperation. According to Follett, what she called her 'Law of the Situation' could be a means for bridging the gap between an ideal of scientific management and the unilateral position that it seemed to involve in practice. In effect she was proposing the same collaboration between leaders and subordinates that was usually to be found between leaders of the same rank.”
