Detection: Evaluation Criteria: Ref:As Per AIAG PFMEA Standards Ril/Pfmea/Annex-C Likelihood of Detection

This document provides an evaluation criteria for assessing the likelihood of detection of issues during a process. It outlines 10 levels of detection opportunity, ranging from "no detection opportunity" to "error prevention". Each level is defined and given a likelihood of detection ranking from 1 to 10. The levels progress from no current process control to error prevention through design. The goal is to have a consistent ranking system to evaluate detection likelihood during process failure mode analysis.

only).
