Lewin's three-step process is regarded as a foundational model for making change in organizations. There is now evidence, however, that Lewin never developed such a model and that it took form after his death in 1947.
This model of change, developed by Lewin, was a simplistic view of the process to change. This original model "developed in the 1920s and fully articulated in Lewin's (1936a) book Principles of Topological Psychology" [8] paved the way for other change models to be developed in the future.
Note it is not merely the experience that causes a change in the "life space", but the acceptance (internalization) of external stimuli. Lewin took these same principles and applied them to the analysis of group conflict, learning, adolescence, hatred, morale, German society, etc. This approach allowed him to break down common misconceptions of ...
It also illustrates other aspects of Lewin's general model of change. As indicated in the diagram, the planning stage is a period of unfreezing, or problem awareness. [ 18 ] The action stage is a period of changing, that is, trying out new forms of behavior in an effort to understand and cope with the system's problems.
Figure 1: Systems Model of Action-Research Process. Lewin's description of the process of change involves three steps: [22] "Unfreezing": Faced with a dilemma or disconfirmation, the individual or group becomes aware of a need to change. "Changing": The situation is diagnosed and new models of behavior are explored and tested.
Lewin's field theory holds that a number of different and competing forces combine to result in the totality of the situation. A single person's behavior may be different in unique situations, as he or she is acting partly in response to these differential forces and factors (e.g. the environment, or E ):
In Lewin's change model he called the first stage unfreezing involving overcoming inertia and dismantling an existing mind-set. He saw this mind-set as a defense mechanism that needed to be circumvented. Change occurs at the second stage — this is a period wrought with confusion as the individual transitions from a previous mind-set to a new ...
His early model of individual change, which has served as the basis of many models of group development, described change as a three-stage process: unfreezing, change, and freezing. Unfreezing: This phase involves overcoming inertia and dismantling the existing "mind set".
