Change models are frameworks that help organizations understand and manage the process of change. They provide structured approaches to guide individuals and teams through transitions, ensuring that changes are implemented effectively. Common change models include Kotter's 8-Step Process, Lewin's Change Management Model, and ADKAR, each offering unique steps and strategies for facilitating change. These models typically emphasize the importance of communication, stakeholder involvement, and the need for a clear vision. By following a change model, organizations can minimize resistance, enhance engagement, and increase the likelihood of successful outcomes during periods of transformation.
