What is a Pareto chart

A Pareto plot displays both the frequency of occurrence, and the cumulative percentage of the total number of occurrences of level of a category variable. It draws its name from an Italian economist, but J. M. Juran is credited with being the first to apply it to industrial problems.

Purpose of a Pareto plot

The purpose of the Pareto chart is to highlight the most important among a (typically large) set of factors. The causes that should be investigated (e. g., nonconforming items) are listed and percentages assigned to each one so that the total is 100 %. The percentages are then used to construct the diagram that is essentially a bar or pie chart. Pareto analysis uses the ranking of causes to determine which of them should be pursued first.
