Negative Positive
Title: Finding the Root Cause
Review: First, let's get the negative stuff out of the way. The first 1/4 of the book contains a lot of comparisons between the author's methods and everyone else's. Not surprisingly, his consistently rates highest. Included are tables with numerical ratings of the different experimental design strategies but no explanation is given for where the numbers come from. Skip it.The meat of the book is its exposition of Dorian Shainin's DOE methodology. I am not claiming to have made an exhaustive survey of the literature on this subject, but he is the only one I have read to offer a workable strategy for sorting through a large number of variables in order to arrive at those that truly control the response of interest without the confounding of main and interaction effects that results from the use of fractional factorials, Taguchi orthogonal arrays and other methods. I have just four more words on this book: try it, it works.
Is the review positive or negative?
