In new product development, faster is not always better. Conceptually, being faster to market should improve financial performance by improving product quality and reducing development expenses. Empirical support is mixed, however, demonstrating that higher speed to market exhibits an inverted U-shaped relationship with product profitability. Conventional wisdom and empirical research suggest managers make speed to market–product quality–development expense trade-offs. A particular concern regarding speed to market is that extreme speed may jeopardize product quality. Some researchers suggest that speed to market improves product quality while others suggest firms must balance both speed to market and product quality. Also, shorter lead times may be associated with reduced development expenses, but empirical evidence is conflicting. This research attempts to reconcile conflicting results regarding the speed to market–product quality relationship, their joint impact on product profitability, and their mediation role in the effects of development expenses and cross-functional integration on product profitability. Partial least squares (PLS) is used to analyze multiplexed archival and survey data collected from NPD managers for 1115 different NPD projects in several firms. The results support the hypothesized equations, explaining 27 % of speed to market variance, 35 % of product quality variance, and 45 % of product profitability variance.
