A Pareto chart is a bar graph that displays the relative frequency or size of problems in descending order of importance. It helps identify the major sources of problems so that resources can be allocated to areas with the greatest potential for improvement. In this case, the manager can use a Pareto chart to identify the time periods where the majority of mistakes occur and focus on improving processes during those specific time slots.
