Twenty-Eight Years to Install Toyota's System

"How Long Will It Take? You can’t blame people for wanting instant results. Time is money, and quickness, especially quick OODA loops, is good. But when it comes to adopting maneuver conflict / Boyd’s principles to your business, there is a lot to be learned and a lot to be done. Consider that: •   According to its principle creator, Taiichi Ohno, it took 28 years (1945-1973) to create and install the Toyota Production System, which is maneuver conflict applied to manufacturing. •   It takes roughly 15 years of experience—and recognition as a leader in one’s technical field—to qualify as a susha (development manager) for a new Toyota vehicle.150 •   Studies of people regarded as the top experts in a number of fields suggest that they practice about four hours a day, virtually every day, for 10 years before they achieve a recognized level of mastery.151 •   It takes a minimum of 8 years beyond a bachelor’s degree to train a surgeon (4 years medical school and 4 or more years of residency.) •   It takes four to six years on the average beyond a bachelor’s degree to complete a Ph.D. •   It takes three years or so to earn a black belt (first degree) in the martial arts and four to six years beyond that to earn third degree, assuming you are in good physical condition to begin with. •   It takes a bare minimum of five years military service to qualify for the Special Forces “Green Beret” (minimum rank of corporal / captain with airborne qualification, then a 1-2 year highly rigorous and selective training program.) •   It takes three years to achieve proficiency as a first level leader in an infantry unit—a squad leader.152"

"Now you are ready to begin acquiring a true intuitive competence. How? By using these skills in ever more complex circumstances so that you build an intuitive feel for situations where there is a lot of stress and the answers are not clear. We do this through incessant practice, incorporating exposure to an ever-widening variety of new and challenging types of situations, and with feedback from knowledgeable individuals (otherwise we’re practicing our mistakes.) We polish individual techniques and also train as a group, thereby building the type of cohesion—mutual trust—that facilitates implicit communication."
