SummaryIt is important to tailor a designed experiment to the real engineering problem, so the results are as useful as possible. The factors and factor levels are critical inputs into the experiment. Their selection should take into account experimental objectives and limitations, as well as previous process knowledge. There is often no single “correct” way to select factors and factor levels. This paper offers guidelines for selecting them, as well as real-life examples illustrating the guidelines and related topics. The guidelines include issues that are usually not considered in any single reference. The guidelines and examples can be used by an engineer or scientist as a checklist to systematically consider issues that may be important for a specific application.
