    I posted a message a few weeks back, looking for starting points on DFSS education. I received one response from Geoff, who apparently has a manuscript ready for print…in several months (thanks again).

    Is there anybody (else) out there?

    Thanks,
    Joe

    Hi Joe
    I do have a lot of material on DFSS… but I am not too sure of what you really want…
    Can you please be more specific.. that way I will be in a better position to assist you…

    Our company Simons-White & Associates offer training and consulting assistance in DFSS.

    You indicated you wanted information on how to start DFSS education. Please be more specific. Are you asking about the curriculum, steps in doing DFSS, tools for DFSS etc.etc.?

    You may want to find a book titled “Six Sigma and The Breakthrough Strategies” by Dr. Mikel Harry and Richard Schroeder. I bought it a month ago because I wanted to learn more about Six Sigma. Harry is the architect of Six Sigma. He developed this when he worked for Motorola. They also offer a Six Sigma Academy out in Arizona. Anyway, back to your question: This book tells all about DFSS as well as any other topic that you may want to know about Six Sigma.

    “[Mikel] Harry is the architect of Six Sigma. He developed this when he worked for Motorola.”

    If you think that Harry was the sole inventor of Six Sigma, he has you brainwashed as much as the rest of the world. The true inventor died in a cafeteria in Motorola. Many others worked on developing Six Sigma as much as Harry. For the full account, read:

    Joe,
    Several companies offer DFSS training…I suggest Sigma Breakthrough Technologies Inc (SBTI)…a company with tested, defined training material and consulting, with a course specifically aimed at Design (not a MFSS redesigned course) The SBTI consultants have been culled from industries and have actually utilized DFSS…including the week one (Customer Needs/Concept generation/Concept Selection). Main phone number is 512-353-7489 in the states.
    What industry are you in?

    Be careful! There are those out there in the world of Six Sigma professing they offer DFSS training…while this may be true from the standpoint of emphasizing the importance of understanding first what the customers expect, few of these DFSS trainers offer the tools/methodologies to statistically predict the performance of a design. Several of these firms offer a version of DFSS that is more project management oriented rather than statistics. My company utilizes several variations of DFSS depending upon what you’re tasked with designing/optimizing. Any good engineer will confirm the importance of statistically predicting the performance of a given design, and then optimizing the design such that the probabilities of failure are sufficiently small (i.e. affordable) BEFORE releasing for production.

    Just a thought…

    There is a new bridge in London – the Millennium Footbridge – which was so well designed by statistical engineers and so well understood and the performance so predictable, that it was not tested in any way before being opened to the public.

    It cost £12,000,000 and 2 years to build.

    Four days after opening it was shut (and remains shut) since it wobbled so much that the real customers using it felt sea sick. It will cost £5,000,000 and 2 years to ‘reduce’ the effect.

    Any real customer will confirm the importance of meeting their inherent needs, and then optimizing the design such that the probabilities of commercial failure are sufficiently small (i.e. affordable) BEFORE releasing for production.

    Just a thought…

    Anon,

    What’s the point? Are there other than “real” customers?

    Just because it was designed by “statistical engineering” (whatever that is) doesn’t mean that the people who used these tools knew how to use them or did a good job of using them. Clearly they did something wrong.

    It appears there were characteristics of the bridge that went unnoticed or at least untested.

    Just because the outcome failed doesn’t imply that the basic methodologies themselves are to blame.

    The space shuttle is another commonly applied example. The models were just fine, except that there was an incorrect assumption that the seals were statistically independent and, therefore, acting as redundant systems. In actuallity they were not independent and when one failed due to cold the others had a much higher propensity to fail – thus BOOOM!

    My point – the methods & tools were valid and useful – the assumptions made were not.

    Thanks Ken,

    I concur! What is a statistical engineer?

    I had the chance to take part in a Six Sigma Champions training during my temporary work in the UK and was really impressed of the  DMAIC methodology I did not know before. Now I´m also very interested in DFSS but it´s difficult to find information in the internet. Who could provide a script or something similar about the theory or practical experiences with DFSS/DMADV? I would like to write an abstract about the topic for my university/ prof.
    Thanks a lot and regards from Düsseldorf, Cici
