Which quality tool is used to identify the most common causes of problems?

• A. Pareto Chart
• B. Checksheets
• C. Flow Chart
• D. Control Chart

Answer: (A)

Focus on prioritizing problems by highlighting the few causes that contribute most to the issues. A Pareto chart uses the Pareto principle, plotting defect categories in order from most to least frequent and adding a cumulative line. This visual shows which few categories drive the majority of problems, so efforts can be targeted where they’ll have the biggest impact. Checksheets are for collecting data on occurrences, not ranking causes. A flow chart maps the steps in a process, helping you see how work moves through the system. A control chart tracks process performance over time and signals when variation is out of control, but it doesn’t identify which causes are most common.
