2. Pareto Diagram

3. Paretos Law The Pareto principle (also known as the 80-20 rule, the law of the vital few Vs. trivial many. 80% of the consequences stem from 20% of the causes. –80% of income in Italy went to 20% of the population. –"80% of your sales come from 20% of your clients. –80% of discipline problems come from 20% of the students

4. Pareto Diagram P. 145 Tool Book What is it? - A bar chart which ranks related measures in decreasing order of occurrence - A tool to separate the significant aspects from the trivial ones - A way to identify the culprit's in a problem and focus improvements in the right area

5. Pareto Diagram How is it made? 1. Select logical categories. 2. Specify the time period. 3. Collect the data. 4. Construct a frequency table. 5. Draw and scale the horizontal and vertical axes. 6. Draw and label the bars for each category 7. Draw the cumulative percentage line. 8. Review the results of the Pareto.
