Connected Process Control, Part 2: Advanced Error-Proofing - Catching Mistakes Before They Become Defects
This is Part 2 of a 4-part series on Epicor Connected Process Control (CPC). Part 1 covered operator-guided assembly. Part 3 covers traceability and reporting to provide full visibility from order to delivery.
A part fails final inspection. Everyone traces it back: the operator followed the instructions, the step was completed, the traveler is signed off. From that perspective, nothing went wrong. Maybe a torque spec was off by a few percent, or a sensor read was out of tolerance, and nobody caught it until later.
Guided instructions (Part 1 of this series) solve the “did the operator know what to do” problem. They don’t solve the “did the machine, tool, or part actually meet spec at that moment” problem. That’s why we’re talking about what error-proofing adds.

What Advanced Error-Proofing Actually Does
CPC connects directly into the devices already on your line through plug-and-play integration: PLCs, sensors, vision systems, badge readers, and more. That connection changes what happens as soon as something goes out of spec:
- The step won’t clear on its own. If a device reading falls outside tolerance, the workflow holds at that station.
- Andon-style alerts pull in help immediately. CPC’s Andon System functionality and event-driven alerts notify the right person either by email or text the moment an issue occurs
- OEE and quality data update in real time, so a developing pattern (not just a single miss) is visible before it becomes a trend across a full production run.
The difference from a traditional catch-it-at-inspection model is timing. Error-proofing moves the catch to the same station before three more just like it get built the same way.

Why This Is a Quality and a Process Outcome
Epicor reports that manufacturers using digital work instructions with CPC have seen defect rates improve by up to 20%. The logic behind it holds up regardless of the exact figure: every error caught at the workstation is scrap, rework, or an incomplete warranty claim.

See It in Action
We recorded a short walkthrough showing CPC’s error-proofing catching an out-of-spec reading in real time. It’s worth the look if you want to see the stop-and-alert behavior rather than just read about it.

What’s Next
Guided instructions get the step right. Error-proofing catches it if something still goes wrong. Part 3 of this series covers what happens after: how traceability and reporting give you, your customers, and your auditors full visibility from order to delivery.
Acuvera Tech helps manufacturers evaluate and implement Epicor Kinetic with Connected Process Control. If catching errors before they become defects is a live problem on your line, we’re glad to talk through what that would look like for you.
