We have roving auditors in our manufacturing process. The roving auditors (who use to be called roving inspectors) main functions is to audit the manufacturing process, beginning with the quality plans, drawings, gages, SPC checks and actually watching the operators perform the operation. All findings from this process are reported as conforming or nonconforming. The roving auditors provide training to the operators when necessary.
Is there anybody out there performing these types of audits in their manufacturing process? If so, do you have any advice or recommendations on perfecting this process?
