Pareto Charts are useful to find the defects to prioritize in order to observe the greatest overall improvement. The Pareto chart is one of the seven basic tools of quality control. Wilkinson (2006) A Pareto Chart consists of vertical bars and a line graph. The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes. The right vertical axis is the cumulative percentage of the total number of occurrences, total cost, or total of the particular unit of measure. 1. [1][2], "What is a Pareto Chart? A Pareto chart is a basic quality tool that helps you identify the most frequent defects, complaints, or any other factor you can count and categorize. This cause analysis tool is considered one of the seven basic quality tools. Budgetary Bandage (Quality Progress) Faced with rising costs of delivering wound care to patients, a public healthcare system in Canada launched an improvement project to find savings, utilizing DMAIC, Pareto charts, and other Six Sigma methodologies. Collect the data, recording the category each time, or assemble data that already exist. In quality control, it often represents the most common sources of defects, the highest occurring type of defect, or the most frequent reasons for customer complaints, and so on. The length of the bars are shown in units at the left vertical axis, and they typically represent frequency of occurrence, but can also be another unit of measure. The maximum value will be the largest subtotal from step 5.

Creating a Pareto Chart A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. According to the Pareto principle, the areas where you have more problems should be the ones that should be addressed first. Decide what measurement is appropriate. The purpose of the Pareto chart is to highlight the most important among a (typically large) set of factors. Use the Pareto chart template (Excel) to create a Pareto chart and analyze the occurrences of up to 10 defects by entering the defects on the check sheet. A Pareto chart, in its simplest form, is a bar chart that arranges the bars from largest to smallest, from left to right. This chart helps project managers find the minor causes that are affecting the project significantly. The bar shows the category values, and the line is the cumulative (all the bars so far added together). A Pareto chart, also called a Pareto distribution diagram, is a vertical bar graph in which values are plotted in decreasing order of relative frequency from left to right.
