Vilfredo Pareto originally observed that in Italy, 80% of the land was owned by 20% of the people. Juran, a 20th century evangelist for quality management, applied this principal to quality control and preferred the use of the phrase "the vital few and the useful many" to describe the 80-20 rule. Quality Management for identifying the most important causes for defects (e.g.80% of the profits come from 20% of the products) 80% of the results come from 20% of the group) 80% of the complaints come from 20% of the customers) Although the actual numbers may be different from case-to-case, the Pareto Principle is a guiding principle used in business for. 80% of the problems come from 20% of the causes)Ī pareto chart can help you quickly identify the most significant factors, but choosing which problems to fix may still require a cost-benefit analysis. If you have a single factor causing 50% of the problems, but it would cost you a million dollars to fix, and there are 3 other factors causing a total of 30% of the problems that would be much less expensive to fix, perhaps solving the 3 other factors first would be more beneficial. The categories in the "tail" of the chart used to be called the "trival many" or the insignificant factors. Juran later preferred to call them the "useful many". For example, what if one of these "useful many" factors contributed to only 3% of the problems, but it was so simple you could solve it immediately at practically zero cost? That is called a "just do it".
