By looking at change as process with distinct stages, you can prepare yourself for what is coming and make a plan to manage the transition – looking before you leap, so to speak. All too often, people go into change blindly, causing much unnecessary turmoil and chaos.
To begin any successful change process, you must first start by understanding why the change must take place. As Lewin put it, "Motivation for change must be generated before change can occur. One must be helped to re-examine many cherished assumptions about oneself and one's relations to others." This is the unfreezing stage from which change begins.
