    I have spent the last few years promoting and training Six Sigma at my company. We have many successful projects dealing with mfg. scrap, rework, variability issues, etc. We are now moving into Design for Six Sigma. It has been a fairly easy fit for mechanical design projects, but the toughest nut to crack has been our electrical circuit designers. I am used to dealing with resistance when presenting these new tools to engineers, but I haven’t been successful getting any of our electronics designers to see the benefit. They insist that Six Sigma only applies to the assembly process end, not the true circuit design. “It’s a waste of my time, leave me alone.” is what I usually hear. Does anyone have a successful approach for demonstrating the benefits of Six Sigma to elctronic circuit designers. Some project examples would be helpful too.

    One option is to appeal to the engineers’ (probably) oversized egos, by asking if they are “up to the task” of implementing DFSS.  You can present 2 major themes:
    1) Use DFSS to optimize product quality (complexity, reliability, failure modes, interchangeability, cost of ownership, VOC)
    2) Use DFSS to take waste out of the design process (design cycle time, time to market, tollgates, errors, manpower)
    Please advise us what changes you make.

    MST,
    I would take a different approach with these guys.  This should actually be a pretty easy one.
    Collect data on them in all the aspects of their process’s that you can get your hands on and use capability measures on them.  If you measure them tie it back to cost and how they impede the rest of the process there should be no argument.  2 + 2 = 4 everywhere, they have defects, variation, rework, failures, Etc.  Just show them their performance. 
    Keep in mind, they will probably have very complicated explanations to justify their performance but the data doesn’t lie (as long as you know the integrity).  If you have to test their explanations (hypo test) or just escalate until they have no choice. 
    Good luck.Scot
    PS I would really like to hear how things work out keep me posted…… [email protected]

    At what company are you?
    A better understanding of your market position might make advice more applicable.

    Many examples of applying design for six sigma in electronic design are available in ITT Industries Annual Taguchi Symposium
