Pareto Chart is a graphical tool to help identify 'Vital Few from Trivial Many'. It is based on Pareto's principle which states that 80% of the defects are due to 20% of the causes. It is a bar chart depicting in descending order the frequency of the different defect categories. The bar chart is superimposed with a line graph which shows the cumulative percentage on a secondary y-axis. As per the principle, approximately 80% of my cumulative defects will be caused by 20% of the defect categories (starting with the categories from far left)
