This is a great book and should be taught at the college along with a supporting statistics package. The essence of the book is in the Placket-Burman fractional designs and how to analyze them. QualPro keeps some of their business secrets and that detracts from the books "useability" and in that respect, the book was a downer. They also put in a few plugs for hiring a "MVT" consultant--which is more like advertising than telling a story. However, the methodology is sound and needs to be used in more areas.
