Hi Everyone,
I have a question regarding family PFMEAs. I'd like to put together a kind of modular
FMEA system to cover all processes at the company like
- incoming material receiving
- internal transport
- warehousing
- melting
- casting/molding
- finishing
- machining
- etc.
- shipping
So my thoughts to have a matrix with all part numbers then group them into families and just make a matrix with marking which module applies to that family. The reason behind this is that the company has over 200 individual PFMEAs currently (in Excel, no software) and they are not maintained but the parts themselves sometimes very similar with minor differences. Processes also similar but of course the machining is creating different product characteristics for each individual product.
For the individual product characteristics, I plan to add a list of all important characteristics as one huge filterable spreadsheet as an appendix to the
PFMEA.
PROS:
- approx. 15 modules PFMEA needs to be maintained in this way instead of the 200+ individual ones
- if I change something in the module that will apply to all PFMEA with uses the same module
- the review takes less time
CONS:
- for PPAPs, I need to put together the modules and save to my PPAP folder as the actual state in the time of submission (can be reviewed by customer on-site)
- hard to add the changes which only apply to one part specifically (e.g X part need higher melt temperature)
- problem with part characteristics
What are your thoughts? Can this work with IATF auditors/customer auditors?
Thank you in advance.
