Its a fact of life: birds flock, fish school, people tribe. Malcolm Gladwell and other authors have written about how the fact that humans are genetically programmed to form tribes of 20-150 people has proven true throughout our species history. Every company in the word consists of an interconnected network of tribes (A tribe is defined as a group of between 20 and 150 people in which everyone knows everyone else, or at least knows of everyone else).In Tribal Leadership, Dave Logan, John King, and Halee Fischer-Wright show corporate leaders how to first assess their companys tribal culture and then raise their companies tribes to unprecedented heights of success. In a rigorous eight-year study of approximately 24,000 people in over two dozen corporations, Logan, King, and Fischer-Wright discovered a common theme: the success of a company depends on its tribes, the strength of its tribes is determined by the tribal culture, and a thriving corporate culture can be established by an effective tribal leader. Tribal Leadership will show leaders how to employ their companies tribes to maximize productivity and profit: the authors research, backed up with interviews ranging from Brian France (CEO of NASCAR) to Dilbert creator Scott Adams, shows that over three quarters of the organizations theyve studied have tribal cultures that are adequate at best.
