I've been away from the Cove for a bit, have read all the comments in this forum and will make sure to visit much more often!! Great work to all!!
I have found in doing FMEA's within a number of industries that the team will get hung up on one column and forget that we are looking for priority numbers to ferret out the most significant problem(s). Keep in mind that severity numbers of a 9 or 10 typically involve safety or damage concerns either with or without notice. A design change may be required to eliminate these failure modes.
Don't be afraid to use high severity numbers. If the occurance is low and detection is high, the RPN will tend to drop this failure mode below radar. If this is not the case, well then the FMEA did as intended.
Consider the use of severity x occurance to calculate the Initial Risk. Typically, IR's of 35 or greater require attention; use the RPN to sort out which ones to work on first. This gets away from the old rules still hanging around out there of RPN's of 100 or greater (or whatever). Some how when those rules are applied it is amazing to find that there are no RPN's that reach that value!
Keep up the great work!
