Experiment Design for Engineers and Scientists: Additional Support Tools for Accurate Decisions

Design of Experiments (DOE) had a profound effect on Japanese production starting with W. Edward Deming’s introduction of these methods in the 1950s. Many of us learned at a very early age that if the product indicated "Made In Japan" then it was not a good product. That has now been reversed. Originally developed as a statistical game by British statisticians, DOE has now become a series of effective tools that have profound implications. Knowledge of the process is not necessary to use these tools. All that is required is to follow a set of instructions to create higher quality products. With statistical knowledge, the set of instructions then becomes more complex and the payback is more profound. Companies that use DOE usually settle on one type of DOE. Aided by a whole toolbox of DOE methods, these companies can now deliver higher reliability and quality products.
