Which of the following tools would help a team of operators to prioritize causes of equipment failures?

A Pareto chart is a quality management tool used to prioritize issues or causes by their overall effect. It is a bar graph that displays the frequency or impact of problems in descending order, combined with a line graph showing the cumulative percentage. This visual representation helps a team quickly identify the "vital few" causes that account for the majority of problems (the 80/20 rule), allowing them to focus their improvement efforts where they will be most effective.

A. Brainstorming is a technique for generating a list of potential causes, not for prioritizing them by impact or frequency.
B. A control chart is used to monitor a process over time to determine if it is stable and in a state of statistical control.
D. A process flowchart is a diagram that illustrates the sequence of steps in a process, used for analysis and understanding, not prioritization.

1. APICS CSCP 2022 Learning System, Module 1, Section C, Topic 3, "Problem-Solving Tools." The material explains that a Pareto chart "is used to identify the most significant factors in a given situation... It helps a team focus on the 'vital few' causes of problems that have the greatest impact."

2. Montgomery, D. C. (2013). Introduction to statistical quality control (7th ed.). Wiley. Chapter 4, "Control Charts for Variables," and Chapter 5, "Process and Measurement System Capability Analysis," discuss the Pareto chart as a fundamental tool for identifying and prioritizing the most significant problems in a process.
