A Presentation by Gary McDonald

Gary McDonald

Dr. McDonald is the former Head of the Operations Research Dept. at General Motors Corp., and the former Director of GM’s Enterprise Systems Laboratory.   He first pointed out the experimenters’ preference for rapid feedback over statistical considerations as motivation for their use of such designs.   Dr. McDonald then described the engineer’s interest in One-Factor-At-a-Time  designs, and the practical difficulties and modeling inadequacies of such designs, e.g., their geometric imbalance, and gave examples.
