Optimal development budgets tied to the marketing mix

The purpose of this paper is to forge a link between optimal levels of the three principal marketing mix instruments—price, promotion and product quality—and the development expenditures devoted to the quality improvement of a firm's existing product. Using the latest operational marketing mix model which prescribes quantitatively what the optimal quality of a brand should be, a simple function relating this optimal quality to desirable development outlays is suggested and some of its implications are explored.
