Introduction of a Change Management Theory   * Lewin’s change model (1951);   * Lewin: the pioneer of change theories;   * Phase 1: unfreezing;   * Phase 2: transitioning;   * Phase 3: refreezing. For the current project, a change model introduced by Kurt Lewin will be used. The theory involves three steps: unfreezing, moving or transitioning, and refreezing (Mitchell, 2013; Shirey, 2013). At the first stage, the preparation for change is performed. Particularly, the team leader recognizes a problem, delineates the need for change, and encourages others to notice the need for change (Shirey, 2013). At the second stage, it is crucial to view change not as an event but as a process. At this phase, a detailed plan of actions is created. The difficulties at this stage are associated with fear and doubt (Shirey, 2013). The third phase presupposes the stabilization of change (Cummings & Worley, 2015). The change becomes integrated into the existing system. Lewin’s Change Model: Strength and Weaknesses   * Strengths:       + versatility;       + practicality;       + simplicity of use;       + easiness of understanding;   * Limitations:       + overly simplified;       + static perspective;       + linear. Lewin’s theory has several crucial advantages. First of all, it is versatile and practical. Secondly, the theory is simple, and it can be employed even by beginning leaders. Also, since the model is old, there is much experience that can be borrowed (Shirey, 2013). Finally, the theory is easy to understand and implement. Although Lewin’s change model is rather popular, there is some criticism concerning it. The major disadvantage is that it may be overly simplistic and cannot be regarded as a scholarly approach. Secondly, the static perspective of the model hinders analyzing a variety of complex modern issues (Shirey, 2013). Thirdly, the present-day healthcare system is non-linear, which makes it impossible to apply the theory to some issues. Step 1: Unfreezing   * Recognizing the problem.   * Outlining the need for change.   * Mobilizing others. At the first stage, I will recognize the problem and mobilize others to notice the need for change. In order to do so, I will inform the community about the seriousness of the issue of homelessness among adolescents and young adults. In particular, I will prepare a report in which significant statistical data will be included. Over 1.6 million of young adults and adolescents in the US are reported to be homeless annually (Haskett, Armstrong, & Tisdale, 2016). Then, I will explain the need to change these drastic numbers. It is the duty of public health professionals, as well as other community members, to eliminate the incidence of young people’s homelessness. Next, I will invite a team of specialists and stakeholders to support the initiative and create a plan of actions. Step 2: Transitioning   * Creating the plan of actions.   * Eliminating doubts and fears.   * Involving as many stakeholders as possible. The second step in Lewin’s change model is moving or transitioning. At this point, it is necessary for a leader to prepare a detailed plan of actions based on the needs of the suggested program. My plan will consist of the following steps: prep
