Process FMEA responsible For "Make to Design Parts" (Inhouse or Suppliers ?)

#1
Dear All,

Need a suggestion, we're a startup aviation industry implementing APQP/PPAP tools.

Question is regarding PFMEA,

We're designing our own Product (levels: System, Sub-System and Components), the initial manufacturing Process (not physical part) will be established inhouse but the individual components (few Sub-systems also) will be manufactured by various identified Suppliers. Typically "Make to Design" approach for potential suppliers.

Suppliers will manufacture as per inhouse Method of Manufacturing /Manufacturing Process Flow --> during the physical product manufacturing phase, method of Manufacturing (Manufacturing Process Flow) may be optimized in collaboration with the supplier.

In this case, for such parts should we create the PFMEAs inhouse? Or Rely on Suppliers PFMEA only?

PS: System Level DFMEA and PFMEA will be created inhouse.

you need to develop FMEA for processes that YOU will use for creation your product. Your product may contain parts that are built in differenr suppliers- they have to have their FMEA analysis for their proccesses of creation those subcomponents for Your product.

*The information & controls received from FMEA & control plan relevant suppliers /materials could be part of input , it's parts of Suppliers development requirement as IATF 16949 also ;
*The operation flowcharts, control plan in prototype stages & DFMEA output should be considered for initial PFMEA
*AIAG manuals regarding APQP , control plans , FMEA /VDA manual & examples of severity ;occurrences score, RPN weighting for components , sub system , --etc --- all of these are basics & fundamentals for initiations

* we should consider also the manufacture activities ; if it's relevant automotive parts ; the score in referenced tables should be followed; otherwise if the products are not relevant for automotive , there's no need for complex criteria of selecting the tighten score ; the score estimation / determination regarding severity / occurrences could be more simple
