What it shows
Process checks (in-process checks, SPC, machine and parameter monitoring) as a share of all categorized appraisal records, against product checks (incoming, final and release inspection). The line below gives the number of checks counted.
Why it matters in manufacturing
Process checks catch drift while it can still be corrected; product checks find defects once they are made. The share shows whether inspection 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; the sparkline shows the share per month. The cost version of this figure is the process control share in the second row.
What good looks like
A share that rises year on year: more of the checks control the process while it runs, fewer inspect the product afterwards.
