A 파레토 차트 is a type of bar graph that represents the frequency or impact of problems in a process. It is based on the 파레토 원리, which states that roughly 80% of effects come from 20% of causes. This chart helps identify the most significant factors contributing to an issue, allowing for focused problem-solving. In a 파레토 차트, bars are arranged in descending order, with the tallest bars on the left. A cumulative line graph may also be included to show the total impact of the factors. This visual tool is commonly used in quality control and project management to prioritize efforts effectively.
