The latest evolutions of quality in the government sector are design of experiments (DOE) principles and statistical engineering. The National Aeronautics and Space Administration and the Department of Defense have been experimenting with test policies incorporating these concepts since 2001. In 2010, the Director of Operational Test & Evaluation published guidelines for well designed and statistically defensible test experiments. For the first time, test programs must report statistical power as a proof of sound design. This article presents the tenets underlying the Department of Defense's DOE efforts, focusing on factorial and response surface design and analyis, statistical modeling and sequential experimentation. A variety of military applications are presented for evaluation.
