Guide
Pareto Charts are named after the Italian economist Vilfredo Pareto. In 1906 he made the observation that 20% of the population owned 80% of the property in Italy. The "20/80" rule has been extended to many areas. The Pareto Chart attempts to identify the 20% of issues causing 80% of the cost, time or loss of quality.
It is plausible that Vilfredo gained his idea from Max Otto Lorenz, who was also studying the inequality of wealth distribution. He presented his graphical representation, including a cumulative line, in 1905.
Identify a time period. Identify categories of cost, frequency or whatever. Categories might be for example, the number of customer complaints; number of defects by type; number of accidents by type; cost of incidents by type. Collect the data for each category and enter the count in the table.
The Pareto Chart may help focus Quality improvement efforts.
Every employee has a role in Quality. Q-Skills3D teaches employees how improve Quality, including how to use and interpret Pareto charts.
