It is often asserted that hearing the voice of the customer (VOC) can generate meaningful product and process innovation. Minimal empirical attention has, however, been devoted to evaluating this claim. The paucity of academic research exists, in part, due to the lack of an underlying conceptual foundation for the VOC concept. An opportunity thereby exists to impart theory, and evaluate whether hearing the VOC can indeed lead to favorable consequences. This research construes customer focus as a market-sensing capability which manifests itself in the key organizational processes (i.e., intelligence generation and continual performance assessment) and values (i.e., a customer orientation serves as the guiding principle) that allow the VOC to be heard throughout the organization. Those manifestations are hypothesized to impact positions (i.e., relative [task-related] performance) and outcomes (i.e., customer loyalty). The results based on data obtained from a cross-sectional survey research design fielded in a supplier-business customer context provide empirical support for the favorable consequences of being customer-focused, and support the need to consider moderating variables. This paper advances theory by (1) answering the call to examine the capabilities that underlie a customer-focused organization; (2) establishing empirical support for the (a) linkage between hearing the VOC and acting on that information, (b) elusive relationship between acting on the VOC and future buyer intentions, and (c) sources→positions→outcomes model as a path to achieving competitive advantage; (3) demonstrating that being customer-focused does not have a direct effect on customer loyalty, thereby revealing a result different than that obtained in the consumer empowerment literature; and (4) demonstrating the importance of key moderators, namely (a) that relative (operational) performance has a strong positive effect on loyalty in relationships characterized by lower switching costs, and (b) that the effect of customer focus may lessen over time, implying that core capabilities may evolve into core rigidities. Additionally, this research contributes to business practice by providing managers with an understanding of how to hear the VOC throughout the firm (i.e., how to become a customer-focused organization), and offering guidance on how to manage buyer–seller relationships.
