常見問題
常見問題
Can a Pareto chart be used for customer complaints?
Yes. Count each complaint reason and sort the categories from most to least frequent.
Why use a cumulative percentage line?
It shows the share of all complaints covered by the leading reasons.
Should complaint reasons overlap?
Use one primary reason per complaint so the category totals can be interpreted clearly.
