The drawing

What a Pareto chart is.

A Pareto chart combines bars sorted from highest to lowest frequency with a cumulative percentage line. It shows which categories account for the largest share of a problem, so a team can choose where to investigate or improve first.

Each category should use the same unit and come from one defined period. The chart helps prioritize observations, but it does not establish why a category is frequent or prove the best solution.

FAQ

Common questions

What is a Pareto chart?

It is a sorted bar chart with a cumulative percentage line that highlights the categories contributing most to a total.

Why are Pareto bars sorted?

Descending order makes the highest-impact categories visible first.

What does the cumulative line show?

It shows the share of all observations accounted for as categories are added from left to right.

Does a Pareto chart find root causes?

No. It identifies priorities for investigation; other analysis is needed to find causes.
