Which description best defines an Error Proofing "shutdown"?

An Error Proofing "shutdown" is best defined as a mechanism that automatically stops the process when a failure is detected. This approach is critical in quality management and Six Sigma methodologies as it prevents defects from continuing through the process. By halting production, it allows operators to address the issue immediately rather than allowing it to escalate, which could result in waste or additional defects in the final product.

This automatic stopping feature is essential in maintaining quality and efficiency in a manufacturing or production environment, as it emphasizes the importance of real-time error detection and correction, aligning with the principles of continuous improvement inherent in Six Sigma practices.
