The Wiley Advantage

  • Includes software examples taken from the four most dominant programs in the field: Design-Expert, Minitab, JMP, and SAS.
  • Focuses on the connection between the experiment and the model that the experimenter can develop from the results of the experiement.
  • Stresses the importance of experimental design as a tool for engineers and scientists to use for product design and development as well as process development and improvement. The use of experiemental design in developing products that are robust to environmental factors and other sources of variability is illustrated. The use of experimental design early in the product cycle can subsatantially reduce development lead time and cost, leading to processes and products that perform better in the field and have higher reliability than those developed using other approaches.
