What it shows
The ten processes with the highest cost in the period, largest first, with the cumulative share of the total and a dotted line at 80%.
Why it matters in manufacturing
A few processes usually cause most of the cost: the Pareto principle, which Joseph Juran brought into quality management as the vital few. Tackling those first gives the largest saving for the effort.
How to read it
The processes before the cumulative line crosses 80% are your priority list. Click a bar to see that process month by month.
What good looks like
A short list of known processes carries most of the cost and gets smaller after improvement work, while the cumulative line rises more slowly as the cost spreads thinly.
