Per IATF 16949:2016, 3.1 Terms and definitions for the automotive industry
Page 12: Error proofing
Product and manufacturing process design and development to prevent manufacture of nonconforming products.
I'm finding "Process design that prevents manufacture of nonconforming product" a difficult concept. I can think of many process design elements that will
reduce occurrence of nonconforming product, but none that will truly prevent it. Does anyone have any ideas?
A past BIQS auditor suggested I interpret "error-proofing" as:
- Auto Shutdown
- Auto measurements or Automatic data collection points
- Auto QMR
- Not auto-advancing
- Intentional System Delays
Problem with this list is that none of these actually meet the IATF definition of "preventing manufacture". The system I implemented mirrors our EHS "error proofing" (snip below), but reading the IATF definition I think this is stretching the requirement to be more than is intended?
Should automated systems that reduce the occurrence of nonconforming product be considered "error proofing"? How would EP devices like this be tested for a simulated failure? They rely on programming which is validated prior to implementation
