Deeper cause analysis during verification/validation phase can many times get into research mode. While the learning out of such analysis will help in future projects, the flip side is that it delays the Start of Production of the project under development. Therefore we are facing the need to give up analysis at some point and take corrective actions accordingly. I am interested to know how this situation is managed generally?
For Example, lets say a Brake liner is not meeting the target life during vehicle level validation. Typically the DFMEA of the liner addresses some potential causes for this failure mode - liner not meeting target life. Preliminary analysis will zero in on one of the causes, example lets say grade of the liner material. Now one option is to stop the analysis here and take actions to upgrade the liner and revalidate. The other option is to further drill down and understand as to what characteristics of the particular grade of liner is not acceptable, etc. The analysis sometimes become even more complicated when the same grade meets required life in a different application. Drilling down further sure helps in enhancing the Design capability of the Organization, but then usually project timelines do not allow the team to do that and hence more often they are merely documented as Things gone wrong at the end of the project.
