    Hi There,
    I am looking for some DFSS material. I have all the DMAIC material but cannot get my hands on the detailed methodology of DFSS

    Can someone please share?

    :)

    There are a few resources out there, but they are a lot less standardized than DMAIC. It would be easier to help if I had an idea of what you need to do with this knowledge.

    It is needed just to give a good overview of what DFSS is to an executive/sponsor group.

    They understand DMAIC and the 12 step process and I wanted to bring them up to speed on DFSS

    Have anything that can help?

    Try searching for DMADV and DMEDI. There are a few other methodology acronyms. DFSS is not as consistently defined as DMAIC. There are quite a few books and other published resources. Kai Yang’s Design for Six Sigma: A Roadmap for Product Development has gotten favorable reviews. Look into the work of Maurice Berryman who has been credited with standardizing DFSS for product development.. About 10 years ago I took a class on DFSS from Berryman and was quite impressed. A consultant for a former employer developed a DFSS for IT methodology for us. I helped him with training and then did QA on IT projects to evaluate how well it worked. It was a different “flavor” of DFSS.

    What your management team needs to know is that since you aren’t beginning with an existing product/service/process this isn’t about incremental improvement. DFSS begins with defining an opportunity for a new product or service, measuring what the market wants (VOC) , then design the product/service and the process that produces it so that it achieves near perfection in the eyes of the customer. Innovation requires inspiration so we probably can’t methodologize that part.

    One of my favorite cartoons shows two guys in lab coats staring at a whiteboard. The left and right sides are covered with formulas, boxes and arrows. In the center is a cloud that says “And then a miracle happens!” The caption is, “I think we need to be a little more specific about this part.” My take on DFSS is that there are many different “flavors” because we want to methodoligize what happens in the middle, but we really can’t. We can facilitate it with techniques such as TRIZ and formal brainstorming, but in the end the miracle happens or it doesn’t. DFSS can tell us what needs to happen and then verify whether or not it works. That’s all.

    Greg Brue wrote a book on DFSS. It’s published by McGraw-Hill, and uses an acronym called IDOV. What I like about the book is that it’s fairly easy to read.

    There are numerous acronyms: IDOV, DMADV, DMEDI, and so on. I agree with Stragydog to an extent: if you are hoping for a major creative breakthrough, luck may have as much to do with it as anything else.

    However, if you want to prioritize what your customers’ needs are, and do your best to ensure that whatever you design meets those needs, the tools and methods of DFSS are valuable. I have applied it both in designing physical products, and in designing non-manufacturing processes.

    Listen to the attached Podcast.

    You will hear about the various versions of DFSS, such DMADV (Define, Measure, Analyze, Design, Verify) and IDOV (Identify, Design, Optimize, Verify), and how the methodology compares to Six Sigma. You will also learn about various critical DFSS tools, such as Quality Function Deployment (QFD), Design of Experiments (DOE) and Failure Mode and Effects Analysis (FMEA) and where you would apply these tools within the design process.

    Fouani offers best practices for how practitioners can be trained on DFSS tools, including Just-in-Time training.

    He also advises that DFSS tools be linked to the Voice of the Customer in order for you to design products that your customer actually wants.

    Raytheon Missile Systems (Tucson) teaches a variant of DFSS called SDM (Statistical Design Methods for Engineers). It is accompanied by Excel based tools that cover all aspects of designing for and managing variability. Scoring is based on fitting data to probability density functions to estimate the actual probability of non compliance (PNC) with specs. I developed the tools and methods and most of the instructional materials for this approach but the course is currently managed by Dr. Al Mense of RMS I think they would agree to teach the course offsite to other companies or gov’t agencies but if you can’t work that out I might help you on a consulting basis
