Pareto Analysis sets priorities for action based on the assumption that roughly 80 percent of problems typically result from 20
percent of the possible causes. Thus, not all possible causes of problems are equally important. Pareto analysis identifies the
most critical causes of problems so that improvement efforts can be focused where the investment of time, effort, and money will
yield the largest return.
1. How would you identify categories about which to collect information from your customers. For example, specify, categories
that describe possible causes or types of defects?
2. How will you gather data and calculate the frequency of observations in each category for an appropriate time period?
3. How will you sort your categories in descending order based on your percentages?
4. Present your data graphically and identify the vital few categories that account for most of the variation.
