“Most people have heard of the “Pareto Principle,” the idea, introduced as far back as the 1790s by Vilfredo Pareto, that 20 per cent of our efforts produce 80 per cent of results. Much later, in 1951, in his Quality-Control Handbook, Joseph Moses Juran, one of the fathers of the quality movement, expanded on this idea and called it “the Law of the Vital Few.”2 His observation was that you could massively improve the quality of a product by resolving a tiny fraction of the problems. He found a willing test audience for this idea in Japan, which at the time had developed a rather poor reputation for producing low-cost, low-quality goods. By adopting a process in which a high percentage of effort and attention was channelled towards improving just those few things that were truly vital, he made the phrase “made in Japan” take on a totally new meaning. And gradually, the quality revolution led to Japan’s rise as a global economic power.3”
