The Origins of Lewin’s Three-Step Model of Change

At the time of his death in 1947, Kurt Lewin was seen as one of the foremost psychologists of his day. He is now best known for his three-step model of change. However, this has been criticized for its “simplicity,” and it has even been suggested that Lewin “never developed such a model,” yet this ignores its links to the rest of Lewin’s work. Surprisingly, there appears to have been no rigorous attempt to understand the connection between Lewin’s early work on field theory and his later work on social and organizational change. In addressing this gap in the Lewin literature, this article will not only show that the three-step model of change is far from being simplistic but also that it was a well-thought-out approach to change based on his development of field theory. The main difference between the two is one of nomenclature rather than substance.
