Pareto Chart. In other words, it’s a vital quality management tool. It’s important to note that not all problems are equally important to solve. It is a highly effective method that is mainly used when the problem statement has been identified by the team members or the investigation team and possible causes for the problem. The defects are classified based on their types. Create a cumulative count of all errors and graph it as a new line. You can create a functional Pareto chart using steps 1 to 5, but you might find steps 8 and 9 provide additional levels of detail. Conversely, 80 percent of a situation's problems can be traced to 20 percent of the causes.
