Pareto Analysis - short version

(1) An economic concept identified by Joseph Juran that argues that the majority of quality problems are caused by relatively few causes. This economic concept is called Pareto's law or the 80/20 rule. Juran dichotomized the population of causes of quality problems as the vital few and the trivial many.

(2) A graphical tool for ranking causes from most significant to least significant. It is based on the Pareto principle, which was first defined by Joseph M. Juran in 1950. The principle, named after 19th century economist Vilfredo Pareto, suggests most effects come from relatively few causes; that is, 80% of the effects come from 20% of the possible causes. One of the "seven tools of quality".

(3) Chart used to identify and prioritize problems to be solved.

(4) A type of prioritizing proposed by Joseph Juran, named for economist/sociologist Wilfredo Pareto.
