Using Design of Experiments as a Process Road Map by Davis Balestracci:
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. It’s hardly an advanced technique, but it leads to much more effective optimization and process control.
DOE is a tool that is very useful. And while the situations in which DOE is the best tool to use is limited the limited use of DOE is used less than it could be. See more articles on the use of design of Experiments (DOE).
