The purpose of the Pareto Chart is to address the most important among a set of factors, the highest occurring type of defect, or the most frequent reasons for customer complaints, and so on. The Pareto principle states that, for many causes, 80% of the effects come from 20% of the causes. A Pareto chart combines an ordered bar chart and a line graph. The left vertical axis represents the frequency of occurrence, while the right vertical axis represents the cumulative percentage of the total number of occurrence. The items on the left side of the chart are called the “vital few” while the rest are considered the “trivial many”.
