The given percentages indicate that the production manager is likely using a Pareto chart, which is used to identify and prioritize the most frequent or important causes of defects. Pareto charts display the relative frequency or size of each cause as a bar graph, with the causes listed in decreasing order of importance on the x-axis and the cumulative percentage of defects caused by those factors on the y-axis. This allows managers to focus their efforts and resources on addressing the most significant sources of defects.
