What tool is used to compare data and identify significant factors in quality control?

• A. Affinity Diagram
• B. Fishbone Diagram
• C. Pareto Chart
• D. Brainstorming

Answer: (C)

The Pareto Chart is a powerful tool used in quality control to identify and prioritize significant factors contributing to problems. This chart follows the Pareto Principle, often referred to as the 80/20 rule, which suggests that a small number of causes (around 20%) often contribute to a large majority (about 80%) of the effects or issues in a given situation. By visualizing data in bars representing the frequency or impact of various factors, the Pareto Chart allows teams to focus their improvement efforts on the most critical areas. This visual representation makes it easy to identify which problems are most significant, thereby enabling effective decision-making regarding where to allocate resources and efforts for quality improvement. In contrast, other tools such as the Affinity Diagram and Fishbone Diagram serve different purposes. The Affinity Diagram is primarily used for organizing ideas and generating solutions, while the Fishbone Diagram is mainly designed to identify root causes of a problem. Brainstorming is a technique for generating ideas and solutions but does not compare data directly or identify significant contributing factors in a quantifiable manner.
