Likelihood of detection

The evaluation of the likelihood of detection in connection with the observed detection action provides the D value in the FMEA.

The evaluation numbers for the D value range from 1 to 10, whereby the number 1 is the most favorable evaluation and the number 10 accordingly represents the least favorable evaluation. Evaluation catalogs exist for the FMEA in the FMEA Handbook by AIAG and VDA. It is recommended to adapt these to suit the respective project. The D value is entered into the risk assessment and TP.

The often held discussion as to whether an action is to be allocated to the detection or prevention category can be decided, for instance, based on the time at which this is carried out.
