(24 Dec 1904 - 28 Feb 2008)
Romanian-American engineer and management consultant who wrote books about quality control management. He popularized the 80/20 rule, which he named after the Italian economist Vilfredo Pareto. The Pareto Principle states that in many situations, roughly 80% of the effects come from 20% of the causes. (Pareto himself, wrote (1896) that approximately 80% of the land in Italy was owned by 20% of the population.)

Science Quotes by Joseph Juran (1 quote)
80% of your work is done with 20% of your tools.
— Joseph Juran
An expression of Pareto’s Principal, also known as the 80/20 rule, the law of the vital few, or the principle of factor sparsity. It is stated in various ways for various situations.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
