What it shows
The part of classified appraisal cost spent on controlling the process while it runs (in-process checks, SPC, machine and parameter monitoring) rather than checking the product afterwards. Appraisal sets without this sub-bucket are left out; the line below says how much of appraisal cost is classified.
Why it matters in manufacturing
Checking finished product finds defects after they are made. Controlling the process prevents many of them from being made at all, which is cheaper and catches drifts early. A growing share means appraisal effort moves to where it prevents failure.
How to read it
Higher is better. The tag compares with the same period last year in percentage points. Read it together with the coverage: with little appraisal cost classified, the share says little.
What good looks like
The share rises year on year while the classified coverage stays high, showing that checking moves from the finished product to the running process.
