    DFMEA/PFMEA and SCCAF alignment

    Hello everybody, I work as a quality engineer for the past year and I am very much interested in DFMEA/PFMEA and SCCAF The engineers where I work are unable to tell me the following: 1 ) should DFMEA and PFMEA be aligned in terms of SC and CC (Significant and Critical Characteristics). When I...

    Where does FMEA fit in your ISO 14971 Risk Management process?

    After reading the FAQ and an article titled "Why FMEA is Not ISO 14971 Risk Management," I get that FMEA is only one tool in the process, but I'm trying to understand where FMEA fits in a typical medical device risk management process, and what additional tasks are needed (and in which order...

    Design for Assembly in DFMEA - Failure Effect of Sub-System(s)

    Hello all, Another recurring problem that I am facing For System A to work, it needs Sub-Systems A.1 and A.2 to be assembled together. In general, a failure of Sub-System A.1 or Sub-System A.2 will lead to a failure of System A. What happens when a Design failure of Sub-System A.1 will mean...

    Design FMEA for a component - Should I make the following assumptions?

    Hello, When doing a design FMEA for a component should you make the following assumptions? -The component meets its specifications (e.g. for a plastic part its meets the dimensions and tolerances specified on the drawing) -The component is suitably designed to meet its intended function...

    Do you need requirements for a Design FMEA

    Hi all, An example of a template for a design FMEA is given in FMEA 4th Edition Blank P and D FMEA sheets in Excel .xls spreadsheets One part I am struggling with is when you do a design FMEA at the component level, do you need to define the requirements for a component. At the...

    DFMEA / PFMEA linkage - Where in the standards do I find it?

    Is there any requirement (current or upcoming) for suppliers to have access to customer's DFMEA in order to complete their PFMEA? I know it's a "best practice", but not all customers are willing to share them. If so, where in the standards do I find it?

    Introducing an existing product into automotive context - DFMEA needed?

    Hi, we have products (fluids) that were designed years ago, that are now being introduced into OEM Automotive applications. The products were originally designed for non-automotive applications, so the design work was done according the ISO 9001 guidelines. Will an auditor have the...

    Development of Design FMEA - Functional Requirements

    In FMEA manual there are 13 categories specified as functional requirements which may be included during design stage e.g. General, Safety......Design for Manufacturability. Now if we take the example of Design for Manufacturability we have been told by customer to split potential failure...

    YS Class in DFMEA & Process Control Measures

    Hi All I am a little stumped! In my DFMEA I have a Sev 8, Occ 3, Det 3 that relates to leakage of an air valve. This does not call for a YS / YC. The reason for occurrence 3 is that we have robustly captured the specification for leakage. We are not design responsible for the valve. We...

    DFMEA Severity 9-10 with Occurrence 3 and Detection 3 - Actions

    If you end up with a failure mode with Severity 9-10 with Occurrence 3 and Detection 3 what approach shall we have? Would it be ok to state "no action" if we can not bring O & D down without design change ? We understand that a design change can solve the dilemma but if that's not the way...

    Determining Effect of Failure without a DFMEA (Design FMEA)

    I just started working with process FMEAs at an organization that does not design products. How do you determine the effect of a failure and the severity without your customer's design FMEA or other input? We can SWAG but not real comfortable with that approach.

    Design FMEA - Where to Start

    HI All I have another PPAP to do - but this one asks for Design FMEA I have done 4 Process FMEAs. Slowly getting my head around it But customers must confuse me with Design FMEA Have no clue where to start - but more importantly Does it really apply to us - we are in the liquid...

    Would a Leak be a Failure Mode on a Design FMEA?

    If the product we are designing includes air springs to cushion a load should leaking be considered a Potential Failure Mode on our DFMEA? There is some thought here that leaks are a process failure not a design failure so leaks shouldn't be on our DFMEA but on our PFMEA.
