DFMEA (Design FMEA) and PFMEA (Process FMEA) - Who should lead?

RPNs aside for the moment, who should lead? What is your definition of lead? I look at this as someone with familiarity with the FMEA process, who knows the correct people to get involved (it is supposed to be a multifunctional activity, no?), and how to facilitate getting the job done, on track, on time, without a lot of side excursions into non-related topics. If that is you, so be it. Nobody says the leader has to be the one to come up with the information.:2cents:

The RPN shouldn't be used by itself to prioritize actions. If you can't use the RPN for prioritization at all, there's no sense in having RPNs.

Added in Edit: I now see that Stijloor was using "standards" to mean trigger or threshold values, and thus my response was not to the point he was making. :bonk:
Jim, my friend...no problem! ;)

Hi,
Interesting thread! As an automotive component product engineering manager, I am experiencing a different form of resistance here at my facility. First of all, most of my engineers are of the old school who strongly believe that the Product engineer is the only person knowledgeable enough of the product to be able to contribute to the DFMEA, and therefore should author the DFMEA alone at his desk without inputs from other cross functions. The other thing that that they claim is that constructing FMEAs in a group meeting format, where one person types on the computer as it displays on the screen is a complete waste of time. The thinking is that 5 or 6 professionals are being paid to watch someone else type into a computer (format columns, add rows, backspace, make corrections, etc.). I of course believe they are missing the cross functional input benefits, but it is very hard for me to break the mental models that have been established at my company in these two areas.

I was wondering if any of you have experience similar resistance at your facilities, and if so, maybe you can offer some tips on how to transition into a more cross functional working environment.

Thanks!
Al

A suggestion:

If you have the time, have one of the old school engineers do the entire analysis on his own, then circulate that document to a number of other stakeholders. If that circulation process results in addition of significant elements to the analysis, your perspective is right for your organization. Then it's just a matter of what collaborative process works best in your corporate culture. Maybe for your company, the sequential-circulation approach would be better accepted as a permanent procedure by busy staff members that perceive themselves to be over-meetinged.

If of course the circulation process doesn't result in addition of significant elements to the analysis, then you might as well acknowledge that the other viewpoint has been right, and procedurize it.

Hi All

In my "former life" I worked in the automotive industry and in that sector the DFMEA was led by a design engineer and the PFMEA by a process engineer. Obviously quality played a major role in the team in both cases and the team was made up of people from various disciplines.

My question is "Is this best practice?" I would have thought the best and most knowledgeable person to lead DFMEA is a design engineer and PFMEA a process engineer. Am I wrong or have I just had it easy for a while?!!

Your comments would be appreciated.
Getting back to the original question, you are absolutely correct that the design engineer should lead the cross functional team in DFMEAs and the Process Engineer should lead the PFMEAs team.

I started training in FMEAs in 1993 and at that time, I would say that 70% of the companies were in "make believe". That is having 1 person sit at a desk developing customer accepted FMEAs making sure that the RPNs were quite low. This is of no value to your company.

I have found that recently about 50% are really doing them as teams and are actually getting something out of it. Management has a lot to do with it. Some feel that there is too much time wasted while others realize the benefit and allow the time.

Hope this helps.
