My boss is asking me to go in and change RPN values on the PFMEA based on a rejection. Can I do this since the PPAP has already been signed off at the customer? Would I have to resubmit the PPAP for customer approval if I change any of the documents? What is the appropriate tool to use here?
Since we are not seeing a pattern of rejections and most are an isolated occurrence, I feel the RPN numbers are relatively accurate. Should this be addressed using an internal corrective action or some other means. We do post Quality Alerts when a rejection happens and if I adjust the RPN number to be higher, wouldn't a corrective action be issued to address the higher RPN number anyway? What satisfies a TS audit?
