A Pareto chart is a vital Six Sigma tool that helps identify and prioritize issues by displaying their frequency or impact. It combines a bar graph and a line graph, with bars representing individual problems in descending order, and a cumulative line showing the total effect. By highlighting the most significant factors (the “vital few”) from the less critical ones (the “trivial many”), Pareto charts enable organizations to focus efforts on areas that will have the greatest impact. This visual tool aids in root cause analysis, quality improvement, and decision-making, driving efficient process enhancements and achieving Six Sigma goals.
