What it shows
The average cost per record of appraisal, internal failure and external failure, on a log scale, with how many times dearer each step is than the one before.
Why it matters in manufacturing
The 1-10-100 rule says a problem costs about ten times more at every stage it escapes. Your own figures show how true that is in your plants, and so how much finding problems earlier is worth.
How to read it
Each bar is per record of that stage, and a record is not always one defect, so read the multipliers as an order of magnitude. Large multipliers make a strong case for prevention and early detection.
What good looks like
Most problems are found early: a short bar for external failure compared with internal failure, because problems are stopped before they leave the plant.
