Pareto Chart is one of the most common tool used in ensuing quality standard in the products. Pareto Chart would help in indicating the percentage of defects occurred over a period of few observations. This would help in estimating whether over a time period the defects are reducing or not. Pareto Analysis is a histogram with values plotted in descending order and presented with a line graph that tracks the cumulative total. Pareto charts are used by quality managers to monitor the frequency of different types of non-conformance events and their causes. Understanding the most common causes of defects allows quality managers to target their efforts appropriate towards reducing incidences of non-conforming product. The lengths of the bars in Pareto Analysis represent frequency of Non-conformance, and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant. This cause analysis tool is considered one of the seven basic quality tools.
