An early model of change developed by Lewin described change as a three-stage process. [15] The first stage he called "unfreezing". It involved overcoming inertia and dismantling the existing "mind set". It must be part of surviving. Defense mechanisms have to be bypassed. In the second stage the change occurs.
Lewin's description of the process of change involves three steps: [18] Figure 1 summarizes the steps and processes involved in planned change through action research. Action research is depicted as a cyclical process of change. The cycle begins with a series of planning actions initiated by the client and the change agent working together.
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 ...
Transformational theory is a branch of music theory developed by David Lewin in the 1980s, and formally introduced in his 1987 work, Generalized Musical Intervals and Transformations. The theory—which models musical transformations as elements of a mathematical group —can be used to analyze both tonal and atonal music .
Lewin's first venture into change management started with researching field theory in 1921. Five years later, Lewin would begin a series consisting of about 20 articles to explain field theory. He would go on and publish Principles of Topological Psychology in 1936, which was Lewin's most in depth look at field theory.
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 ):

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. [22] The action stage is a period of change, that is, trying out new forms of behavior in an effort to understand and cope with the system's problems.
