Design of experiments (DOE) is a statistical method for identifying which factors may influence specific variables of a product or process under development or in production. DOE should be used during the Plan Quality process to determine the number and type of tests and their impact on cost of quality.
DOE also plays a role in the optimization of products or processes. DOE can be used to rcducc the sensitivity of product performance to sourccs of variations causcd by environmental or manufacturing differences. One important aspcct of this technique is that it provides a statistical framework for systematically changing all of the important factors, rather than changing the factors one at a time. Analysis of the experimental data should provide the optimal conditions for the product or proccss, highlight the factors that influcncc the results, and rcvca! the presence of interactions and synergism among the factors. For example, automotive designers use this technique to determine which combination of suspension and tires will produce the most desirable ride characteristics at a reasonable cost.
