Kurt Lewin’s methods of planned change and Edwin Friedman’s self-differentiated leadership are blended together and illuminated through the true story of legendary Malaysian businessman Chan Koh. Crafted as a workbook with quizzes and self-assessment worksheets, this is a concise and entertaining organization development masterpiece. The author’s also draw from their own decades of experience to further illustrate their approach to Lewian OD. Gilmore Crosby is a foremost expert on Lewin and brings fresh clarity to Lewin’s practical and reliable concepts such as field theory and group decision. His companion work, Planned Change: Why Kurt Lewin’s Social Science is What the World Needs Now for Leadership, Business Performance, Change Management & Social Change, is a deep dive into and a new organization of Lewin’s original writing. It is due out in 2020 from Taylor & Francis and has been endorsed by many of the leaders of the OD profession. The Chan Koh story benefits from the same research and combines Friedman and Lewin in a simple yet powerful way. The cross-cultural element is the icing on the cake of this OD gem.
