The graph shows that just about 80% of the effects are coming from 20% of the causes. The connected data points above the bars represent cumulatively what each team is contributing as a percentage to the total number of defects. The percent under the count of defects shows what percentage of the total defects that team was accountable for. Team 4, with 25 of the 50 total defects, was placed on the left. The chart created by Minitab has sorted the teams in descending order by the number of defects create. In this example your effects are the defects and the causes are the teams. The purpose of running a Pareto analysis on this data set was to find how many defective products were being created by each team.

It shows the count of defects across five different teams. The data used in the following example can be downloaded in. Steps to Running a Pareto Chart in Minitabīelow are step-by-step instructions on how to run a Pareto chart in Minitab. By creating the Pareto chart, areas of concern are easily identifiable. The chart identifies the Pareto principle, or what many call the “law of the vital few,” or more often, the “80:20 rule.” The principle suggests that a majority of the effects are coming from a small amount of causes. One of the most useful charts to visually represent where areas of concern in a business may be is the Pareto Chart.
