1- Pareto Chart
Also called: Pareto diagram, Pareto analysis
A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way, the chart visually depicts which situations are more significant.

- Decide what measurement is appropriate. Common measurements are frequency, quantity, cost and time.
- Decide what period of time the Pareto chart will cover: One work cycle? One full day? A week?
- Collect the data, recording the category each time. (Or assemble data that already exist
