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. A Pareto Chart is a graph that indicates the frequency of defects, as well as their cumulative impact. Common measurements are frequency, quantity, cost and time. The bars are placed on the graph in rank order, that is the bar at the left has the highest contribution to counts or cost. The individual values are represented by the length of the bars and the line shows the combined total. Calculate and draw cumulative sums: add the subtotals for the first and second categories, and place a dot above the second bar indicating that sum. A Pareto chart follows the 80/20 principle developed by Vilfredo Pareto, an Italian economist in the early 20 th century. Decide what categories you will use to group items.

Connect the dots, starting at the top of the first bar. Pareto chart helps to Narrow problem area or prioritize the significant problems for corrective measures.. Pareto Chart based on Pareto 80-20 rule.It means that 80 percent of the problems/failures are caused by 20 percent of the few major causes/factors which are often referred as Vital Few.. And the remaining 20 … A Pareto chart is a data-based approach to determining what “vital few” issues you should be working on. Pareto chart is a graphical representation of Pareto analysis. The left vertical axis is the frequency of occurrence, but it can alternatively represent cost or another important unit of measure. 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 lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right.

To further illustrate, the Pareto chart has been designed as a visual representation of the vital few against the trivial many. The bar shows the category values, and the line is the cumulative (all the bars so far added together). Figure 2 takes the largest category, "documents," from Figure 1, breaks it down into six categories of document-related complaints, and shows cumulative values.

A Pareto chart (also called Pareto diagram, or Pareto analysis) is a bar graph. A Pareto chart is a specific type of histogram that ranks causes or issues by their overall influence. The left vertical axis of the Pareto chart has "counts" or "cost" depending on the data used. Because the values are in decreasing order, the cumulative function is a concave function. A Pareto chart displays the frequency of cases, as well as the accumulated percentage of these cases.
