SPC Factory Simulator

Step into the shoes of a quality engineer. Can you catch the problem before bad parts ship?

You Are the Quality Engineer

It's 6:00 AM. You just clocked in for first shift at a juice bottling plant. You're responsible for monitoring fill volume on a high-speed filling line that produces 330 mL mango nectar bottles. The night shift operator says everything ran fine, but you know better than to take anyone's word for it -- you check the data. Your control chart is your eyes on the process.

Today's Assignment

Your filling line has been running stable, but something is about to change. A new ingredient lot just arrived, and a hidden process event will occur during your shift. Your job is to detect it on the control chart, stop production before underfilled bottles ship, dig through the factory logs to find the root cause, and annotate the chart like a real quality engineer would.

How This Simulator Works

Watch the Chart

A live X-mR control chart plots one measurement every few seconds. The process starts stable. Watch for trends, shifts, or rule violations.

Stop Production

When you see something wrong, hit the red STOP button. The longer you wait, the more bad parts ship and the lower your score.

Investigate the Logs

After stopping, 5 factory logs appear: Raw Material, Operator, Maintenance, Environment, and Tooling. The root cause is hidden in one of them. You must find it.

Annotate and Score

Select the root cause, mark the chart where the problem started, and write an annotation. You'll be scored on detection speed, investigation accuracy, and annotation quality.

Don't wait too long! If too many out-of-spec parts ship before you stop production, the scenario fails with a customer complaint. Just like real life.

The chart will begin plotting immediately. Stay alert.
