To all those wondering “Why?” and “How?” certain organizations are more productive than their peers, Logan, King and Fischer-Wright have some concrete answers. In their landmark book, “Tribal Leadership”, they explore the essence of organizational culture. What they have uncovered is a dynamic at least 15,000 years in the making, and at the heart of all human organizations: the tribe. We operate in a “tribe”-a group of 20 to 150 people- in which important decisions are made and productivity is determined. Larger organizations are “tribes of tribes”. Five stages describe the evolution of the tribe, from savage and dysfunctional to innovative and powerfully inspirational. What sets this work apart is its practical advice on both identifying the stage of the tribe and the means to advance to the next stage. Laced with real-life examples, the book is eminently readable. There is no doubt it will transform the reader, no matter where their own tribe finds itself. They will understand the difference between leading and commanding.
