Kurt Lewin's work on change management dominated for over 40 years, but recent criticisms have questioned its relevance. These criticisms include assumptions of organizational stability, suitability for small-scale changes, neglect of power and politics, and a top-down approach. This article re-evaluates Lewin's contributions, emphasizing his commitment to resolving social conflict and his integrated approach to planned change through Field Theory, Group Dynamics, Action Research, and the 3-Step model. Despite criticisms, Lewin's work remains relevant today. His background as a German Jew influenced his focus on democratic values and social justice. Lewin's research on group dynamics and action research laid the foundation for organizational change, and his 3-Step model of change is still widely used. However, newer perspectives, such as Culture-Excellence, processualism, and complexity theories, challenge the simplicity and linearity of Lewin's approach. These newer models emphasize continuous, dynamic change influenced by culture, power, and politics. While Lewin's work has faced criticism for being too simplistic, it is still seen as a foundational approach to change. His emphasis on understanding and addressing social conflict remains relevant, and his work continues to influence organizational development and change management.Kurt Lewin's work on change management dominated for over 40 years, but recent criticisms have questioned its relevance.
