Force field analysis is a management technique developed by Kurt Lewin for diagnosing organizational situations and driving change. It involves identifying the driving forces that promote change and the restraining forces that inhibit change. When these sets of forces are balanced, the situation is in a state of equilibrium. The technique can be used to identify performance problems, evaluate alternative solutions, and prioritize actions needed to implement change by reducing restraining forces and increasing driving forces. It involves listing the forces, assigning scores to their strengths, and diagramming them to analyze how to move from the current state to the desired state of change.
