  "Back in the lab, I tackled ink with DOE. I was able to perform a small number of experiments and learn about interactions among the ingredients. I could see which ingredients appeared to be the most important, which ingredients interacted, and which inte

• Maximize Test Coverage Efficiency And Minimize the Number of Tests Needed by John Hunter
  "The steeper the slope the more efficient your test plan is. If you repeat the same tests of pairs and triples and… while not taking advantage of the chance to test, untested pairs and triples you will have to create and run far more test than if you intelligently create a test plan. With many interactions to test it is far too complex to manually derive an intelligent test plan. A

• Do Interactions Matter? by George E. P. Box
