The commercial success or failure of a product doesn't rest solely on the whims of the marketplace. The myriad, often interdependent strategic trade-offs made throughout the product development process go a long way toward determining whether a product succeeds or fails. The key to success often rests in finding the right combination of product design and market choice decisions. Toward that end, William E. Souder and X. Michael Song examine the relationship between product success and several product design and market choice strategies. In particular, they explore the possibility that the correct strategy combination differs depending on a firm's perception of market uncertainty, which they measure in terms of the respondents' perceived familiarity with the market for a product, perceived understanding standing of customer needs, and perceived capability to translate those needs into product performance specifications. Recognizing that the correct combination of strategic choices may also depend on firm size, industry, and culture, the study focuses on small U.S. suppliers of electronics components. Fortune 500 producers of electronics final products, and Japanese producers of electronics final products. For the small U.S. firms in the study, an emphasis on performance superiority, technical superiority, or radically new products provides a recipe for failure under low market uncertainty. Even under high market uncertainty, these characteristics do not equate to success for the small U.S. firms in this study. The findings suggest that these firms should focus on design compatibility with a purchaser's installed base. The responses from Fortune 500 firms and Japanese companies indicate that under low market uncertainty these larger organizations should consider emphasizing compatibility and avoiding radical designs. For markets that the larger firms perceive to be highly uncertain, the results suggest that these companies should emphasize performance superiority, technical superiority, and radical designs. The findings related to market choice strategies also support the notion that the correct combination of strategic decisions depends on firm size, culture, and the perceived level of market uncertainty. However, the guidelines presented in this study should not be construed as hard-and-fast rules for formulating product strategy. Instead, the results presented here will be helpful for challenging assumptions and guiding actions, as one element in the effort to shape an effective product strategy.
