According to Lewin, successful change requires unfreezing the status quo, changing to a new state, and freezing the new change to make it permanent. The status quo can be considered an equilibrium state. Unfreezing is necessary to move from this equilibrium. It can be achieved in one of three ways:• Increase the driving forces, which direct behavior away from the status quo.• Decrease the restraining forces, which hinder movement from the existing equilibrium.• Do both.
