The change process is the way to transform, a way to redefine and realize a new vision for the moving ahead in life. The task which looks simple in plans is in actual a very complex in its execution. It requires moving through several stages and executing different tasks: this includes

1. Performing an organizational audit,
2. Planning,
3. Formulating the change strategy,
4. Communicating,
5. Persuading others, and
6. Consolidating the change.

 It takes effective transitional leadership (at the individual, group, and organizational levels) to accomplish all these activities.

 One of the earliest and most widely used change process theories is the force-field model.

This model proposed that the change process is divided into three phases:

Phase 1 : Unfreezing,

Phase 2 : Changing, and

Phase 3 : Refreezing.

Human mind is quick to find the escape route once it conceives the idea of resistance to change

 A more recent theory is the eight-stage model of planned organizational change. The two models complement each other; however, the difference between the two models is in the implementation phase.

The eight-stage model of planned organizational change provides considerably more detail in the implementation phase than does the force-field model. It stipulates eight sequential steps compared to one step (the changing phase) for the force-field model. The steps in the eight-stage model are:

1. Establish a sense of urgency.
2. Form a support platform (pro-change coalition).
3. Develop a compelling vision.
4. Diffuse the vision throughout the organization.
5. Train and empower followers to act on the vision.
6. Allow for short-term accomplishments, and reward performance.
7. Consolidate gains by changing the culture, systems, policies, and structures to align with the new vision.
8. Institutionalize the change in the organizational culture.
