What it shows
Quality activities per month as shares of 100%: proactive (planned prevention and process checks) against reactive (product checks, reactive prevention and failures). It is the north star of the page, month by month.
Why it matters in manufacturing
A single month can mislead; the trend shows whether quality work keeps moving ahead of problems.
How to read it
Look for the dark band to grow. Hover a month for the shares and the number of activities.
What good looks like
The proactive band widens month after month and holds, also in busy months.
