Article Abstract

[This abstract is based on the author's abstract.]

An approach to testing large systems using experimental design techniques is presented. With the use of such techniques, test cases can be selected that quickly find and isolate errors. A simple experiment on a manufacturing process serves to demonstrate basic experimental design concepts. The experiment is converted to a Taguchi array to enhance results, and the array is then reduced to speed up the testing process with a minimal loss of information. A complex software system is described. A scenario is presented showing how test time can be reduced dramatically using a large Taguchi array.
