I have been trying to do a FMEA for process Planning (travelers) and having alot of problems. does anyone have an example of one such animal, having problem with the SEV and the OCC the DET, somethings just dont fit especually if its a purchase order problem, if the blame is not on us our RPN still goes up. how do i prevent that.


Thank you.

We already went through this in this thread Is FMEA for Process Planning Necessary? (http://elsmar.com/Forums/showthread.php?t=17043)

If you can be more specific regarding the FMEA line you're having problems with, we can help. If I understand you correctly, problems that don't originate in the process in question shouldn't be addressed in that process; they should have been dealt with upstream. Of course, it depends on what sort of purchase order problems you're referring to.

Good Morning Jim. I work in a platting shop and so we recieve alot of P/Os that are incorrect where as we have to call them tell them to send a corrective p/o ect. such items like that, our planners are also our contract review(ers) so doing a FMEA on Process planning (Travelers) just having problems with responsibility

thank you

The stage where planners receive POs and review them is what you're concerned with. It's similar to receiving inspection, in that you should focus only on your own company's process, and not the customer's. In other words, assuming that the condition of incoming POs is unknown, what are the potential failure modes of your process? Failure to detect a "bad" PO is one possibility, as is rejecting a "good" one. What controls are in place for detection? What is done to prevent errors from happening when POs are reviewed? These are the questions you need to answer in the FMEA process.

I see a number of "opportunities":


Some of the descriptions of categories are questionable, such as describing the potential failure mode as "...ways the key input [might]go wrong." You should assume that the state of input (the customer PO) is unknown, and deal with potential errors in your process. Also, under "Current Controls," there are a few problems: the information called for is "...the existing controls and procedures (insp & test) that prevent either cause or failure mode?" You shouldn't limit your self to inspection and test (which are detection controls), and you can't prevent the failure mode without addressing the cause. You need to describe two types of controls: those for detection, and those for prevention. How are "bad" POs detected? How is faliure to detect a bad PO prevented?
You cite "contract review" as one of the current controls for each potential failure mode, but this FMEA is about contract review, no? You're going in circles.

I see what you saying about going in circles since i am doing a FMEA on contract review. contract review can not be the answere. I think the problem is i have never had to do a FMEA and learning as i go.

Like I said in the other thread, you shouldn't be doing it by yourself, especially if you lack experience. FMEA has to be a group exercise if it's going to do any good.

Yes i got the planners together and came up with what i sent you.
