Product optimization: approaches and applications

In its most general sense, the phrase ‘product optimization’ stands for the disciplined approach to product development, whereby the investigator systematically varies formula and processing conditions. In recent years product optimization has become an increasingly valuable tool for development, because it cuts time, cost and risk in the development process (Baxter, 1989;Box et al., 1978;Gordon, 1965). This paper presents a history of the approach from the viewpoint of applications, followed by an illustrative case history.
