As the number of organizations implementing action learning increases, both successful and failed cases also increase in action learning practice in South Korea. Existing studies on action learning have listed key success factors of action learning at the program level or at the team level but have not paid sufficient attention to the program design process itself. The purpose of this study was to show how to develop a design model of action learning that incorporates a step-by-step decision-making process and that provides design principles necessary along the way. This design model will present the importance of contextualizing the action learning process by asking "highly required" questions and help raise the level of successful implementation of action learning programs.
