Kurt Lewin's change management model indicates that environment has a great impact on shaping the people's behavior. As we can see in the picture individuals' behavior is like an ice in the environment and can be shaped according to that. Moreover, according to this model behavior only can be changed when dissatisfaction and discomfort happen because they can work as a motivator through the change.

Kurt Lewin's change management model consist of three different stages that we are going to discuss below:

Unfreezing: Refers to the dissatisfaction or frustration with the way things are. In this phase we need to make sure to communicate effectively with the people within the company to address their doubts and concerns.

Changing (Move): In this stage, the old patterns of behavior will be changed. Based on this phase people will get used to the idea of doing things differently in a way that can align with the intended change. Moreover, people need to get motivated to involve in the change process.

Refreezing: It happens when the new pattern of behavior replace the old ones. In other word, this will happen when the change has been successfully implemented and become part of the organizational culture. It is worth mentioning that people receive sufficient support from the organization and managers for making the change happen. Lastly, the change process need to continuously get monitored to make sure about the effectiveness of the change implementation.

Step One (Create Urgency): This step indicated the necessity and urgency of the change by identifying the potential threats and opportunities that exist during and after the change implementation (Mind Tools, n.d.)

Step Two (Build a Coalition): According to this step leading the change, creating effective teams, and allocating different responsibilities to the team members is essential for implementing the change successfully (Mind Tools, n.d).

Step Three (Create a Vision for Change): This step focuses on determining the goals and objectives of the change, creating an image about what will happen upon this change, and planning the processes that need to go through to reach the desired result of the change.

Step Four (Communicate the Vision): After creating a vision for change the leaders need to discuss it with the employees and share a clear image of the process and future of the change by using both formal and informal approaches (Berteig, 2020).

Step Five (Empower Others/ Remove Obstacle): According to this step removing barriers such as employees’ resistance and structural issues will help to empower employees for more effective change implementation (Berteig, 2020).

Step Six (Create Quick Wins): This step indicates the importance of setting small and achievable goals in order to motivate employees and create a positive trend toward the intended changes.

Step Seven (Build on the Change): According to this step leaders need to track the progress and seek continuous improvement by measuring and assessing the Change (Consuunt, 2021).

Step Eight (Embed the Change in the Corporate Culture): This is the last step of Kotter’s model and refers to incorporating the change and sustaining it into the organizational culture.

when it comes to Bridges Transition model we need to keep in mind that there are difference between change and transition because change can happen at once while transition refers to a process that can be completed through a period of time.

This model consists of three stages, which is very similar to Lewin's model in this case, and the stages are as bellow:

Ending, Loosing, and Letting go: This stage refers to ending and saying goodbye to current pattern

Reaching to neutral zone: In this stage we need to utilize our skills to grow. Therefore, the process and the future in terms of what is going to happen next, should be clear in order to increase productivity.

The new beginning: When utilize skills, technology and all the people come together with assist of managing transition. This stage can indicate a successful change implementation change.

Examples in business world can be:

• Sony: The transition from video tapes to DVDs and applying the required technologies for this transition.

• Philips: Their journey from producing lighting systems to becoming one of the medical equipment manufacturers.

Example in our daily life can be the process of immigrating to another country which has 3 different phase such as leaving your life, family and friends in your country to come to a place with more opportunity to grow and usually you are so excited about coming to the new place, then when you come to the new place after a while you will realize the differences, difficulties and sometimes feel down about this change. However, in this stage you need to improve your skills continuously to pass this process successfully. Ultimately, we can adapt to the change and start a new beginning in new country.
