"The current design of experiments (DOE) renaissance seems to favor factorial designs and/or orthogonal arrays as a panacea. In my 25 years as a statistician, my clients have always found much more value in obtaining a process "road map" by generating the inherent response surface in a situation."

"People donâ€™t need statistics; they need to know how to solve their problems. All thatâ€™s needed is a few simple tools and a working knowledge of variation to be able to distinguish between common and special causes. Only 1â€“2 percent of people need advanced statistical knowledge...
'Prediction is the problem, whether we are talking about applied science, research and development, engineering, or management in industry, education, or government,' [Deming] says. 'The question is, 'What do the data tell us? How do they help us to predict?'"
