The Pareto principle (also known as the 80-20 rule, the law of the vital few and the principle of factor sparsity) states that, for many events, 80% of the effects comes from 20% of the causes. Business management thinker Joseph Juran suggested the principle and named it after Italian economist Vilfredo Pareto, who observed that 80% of income in Italy went to 20% of the population. Later, Pareto discovered that the principle was valid in other parts of his life, such as gardening: 80% of his garden peas were produced by 20% of the peapods.
