In a Network Industry,Does Product Quality Matter?

The role of product quality in industries influenced by network effects has been the subject of significant debate among management theorists. Some have suggested that network effects can result in inferior products, as consumers value a large cohort of fellow adopters over the technical quality of a given product. Others argue that cases of market domination by inferior products are quite rare and that product quality is an important aspect of network‐based competition. Thus, a fundamental question has arisen from this debate: in industries influenced by network effects, does product quality matter? This research uses a sample of product releases in the application software industry from 1986 to 1998 to test the impact of product quality on installed base growth for a given product line. Using software quality measures from archival trade publication reviews, quality is found to have a positive and significant impact on growth, even after controlling for installed base size and other product, firm, and segment characteristics. This finding suggests that the first‐mover advantages often ascribed to network industries may be more complex than previously thought. Rather, effective strategy in network competition appears to center on the trade‐off between early product releases, with the intent of establishing an early installed base, and later product releases, with the intent of improving the quality of the focal product. Several potential extensions of this work are offered, with a specific focus on (1) the impact of variation in the strength of network effects across industries, and (2) the dueling incentives faced by incumbents in network industries, who may possess greater capabilities to produce high‐quality products but limited incentive to do so. Other potential contributions for theory and practice are offered and discussed.
