What is a Pareto Chart used for in quality management?

A Pareto Chart is an essential tool in quality management that graphically represents the separation of the vital few from the trivial many. This concept is rooted in the Pareto Principle, also known as the 80/20 rule, which suggests that a small number of causes often lead to the majority of problems or defects in a process.

By using a Pareto Chart, organizations can visually analyze the frequency or impact of different issues, allowing them to identify which problems are worth addressing first based on their significance. The chart typically displays categories of data in descending order, enabling quick identification of the most impactful areas requiring attention. This prioritization is crucial for effective quality management, as it allows teams to focus their resources on solving the most critical problems, ultimately improving overall quality and efficiency.

The other choices address different aspects of quality management, such as measuring performance, tracking production volume, or monitoring costs, but do not convey the unique purpose a Pareto Chart serves in identifying and prioritizing quality issues.
