Product change intensity, product advantage, and market performance:: An empirical investigation of the PC industry

Product change decisions, such as the frequency of new product introductions, can impact product performance characteristics, sales, and market share of several generations of products and, therefore, a firm's long-term survival and growth. The purpose of this study was to explore the impact of a firm's product change frequency, also referred to as product change intensity. A conceptual model linking a firm's product change intensity to its product advantage-and, in turn, to its market performance-with strategic product change orientation and technology competence as moderating effects, was used as a foundation for the study's hypotheses. These were tested using hierarchical and linear regressions, based on survey data collected from 55 U.S. companies in the personal computer (PC) industry. The analysis confirmed that a PC firm's product rate of change is positively associated with its product advantage and that its product advantage, in turn, is positively associated with its market share and growth performance. However, the hypothesized moderating effects were not confirmed. Rather, a firm's product change orientation and its level of technology competence are more likely to have a direct impact on product advantage. The implications of these findings are that, in general, firms that release new products frequently will have them viewed more favorably by the market than products with lower change intensities. Also, firms with higher levels of competence in the product technology domain tend to create products with greater market attraction. Finally, more radical changes to PC product architectures may pay off better than relatively minor changes. These results may not apply to other industries due to the specific design of personal computers and the nature of this fast-paced market. Neither do the findings necessarily apply to all firms regardless of those firms' specific product and market strategies. More research is necessary to understand how a firm's adopted strategy, and the industry in which it operates, affect the relationships demonstrated in this study.
