Pareto Chart

Pareto ChartPareto charts display defect codes and causes in a simple, easy-to-understand bar chart. But don’t let their simplicity fool you—these charts can be useful statistical process control (SPC) analysis controls. 

A traditional use of a Pareto chart like the one shown here would be to count and categorize the types of potential defects that result from a visual inspection of an engine. You can see from this example that the defect “Incorrect Torque” is most prevalent.

Multilevel Pareto Charts

Multilevel Pareto Charts
InfinityQS® software takes Pareto charts a step farther by enabling multilevel charts. With these robust, sophisticated tools, you can sort and display defect codes by shift, customer code, employee, lot number, part—and descriptors that you tag to the data. Following the previous example, you can now determine not just that the most prevalent defect is “Incorrect Torque,” but also the following:
  • The number of “Incorrect Torque” defects that occurred on specific engine numbers
  • The total number of defects for each defect code
  • The total number of defects of each type for each serial number

With the power of multilevel Pareto charts combined with other SPC tools, like box-and-whisker charts, InfinityQS solutions make it possible for manufacturers to quickly identify and prioritize process variation and product defects. You can switch filters and views of Pareto charts, drill down into specific details for specific products, parts, lines, or sites, and more.
