    There are certainly articles to be found, most of which are of the academic or sales type. That’s nice, but skeptics aren’t easily sold on the concepts. Many feel that DFSS and related methods are nothing more than extra work. However in error those opinions might be, you are left to debate the merits without the benefit of tangible information.

    I have to disagree about “no baseline.” Business metrics are moved all the time based on success of designing new business processes. However unstable a product development process may be, time to market, development costs and mistakes avoided can be measured. The problem is showing that it is the implementation of best DFSS practices that is the factor – other improvement factors could have been just as key if not more so.

    The PERT distribution is an “expert opinion” distribution that is similar to a triangular one, except that it has a smooth curve. It is useful for estimating schedule risk. There are uses for the general Beta distribution, but in my experience, and in talking with other experts, they are mostly of theoretical interest and have little industrial application.
