What is Design of Experiments?

E xperimental Designs are used to identify or screen important factors affecting a process, and to develop empirical models of those processes. Design of Experiment (DoE) techniques enable teams to learn about process behavior by running a series of experiments, where a maximum amount of information will be learned, in a minimum number of runs. Tradeoffs as to amount of information gained for number of runs, are known before running the experiments. For example, a designed experiment has three factors; each set at two levels - typically the maximum and minimum settings for each of the factors.
