The five essential steps in developing a new product namely: 1) Product concept, 2) Review of technology and compatibility with company objectives, 3) Experimental design, 4) Experimentation, and 5) Analysis of Results are reviewed. The role of the Quality practitioner in guiding the management decisions, designing the experiments and evaluating the results is emphasized. An innovative approach using the combination of mixture and factorial designs with a reasonable number of experimental trials is described. The development of a muffin line extension for the Aunt Lucy Donut Shoppe Division of a hypothetical major food corporation is used to demonstrate these principles.
