What is Design of Experiments (DOE)?
Design of Experiments, or DOE, has been in practice since the early 1900’s. Developed in England, R.A. Fisher led the initial applications in the field of agriculture. Other contributors to Designed Experiments have included Rao, Plackett, Burman, Box, Taguchi, Barker, Derringer and many others. Until the early 1980’s, Designed Experiments were usually set up and run by specialists within an organization. Today, with the advent of readily available software, such as DOE Wisdom, the non-statistical person can successfully set up and analyze simple but powerful experiments. A designed experiment is a well-controlled family of tests. Each test is run one or more times. For each controlled test, outputs, also known as responses, are measured. From test to test controlled changes will be made. Once the tests are completed, the data can then be analyzed. As you will see with further understanding of designed experiments, simple graphs can be of great value in furthering your understanding of
