A Pareto chart is a type of bar graph that visually represents the frequency or impact of problems or causes in a process, helping to identify the most significant factors. The bars are arranged in descending order of height, while a cumulative line graph overlays the bars to show the total impact of the factors cumulatively. This tool is essential in identifying the 'vital few' issues that contribute most to an overall problem, allowing businesses to focus their efforts on the areas that will yield the greatest improvement.
