Change Theory is a framework that helps understand how and why change occurs within organizations and communities. It outlines the processes involved in transitioning from a current state to a desired future state, emphasizing the importance of planning, communication, and stakeholder involvement. Key components of Change Theory include recognizing the need for change, creating a vision, and implementing strategies to achieve that vision. The theory also highlights the significance of evaluating the change process to ensure it meets its objectives and to make necessary adjustments along the way.
