The purpose of this article is to investigate how competitive intensity impacts the relationship between crucial firm resources (human capital, organizational capital, management capability) and firm performance. Using a sample of 105 service providers from the Indian information technology–enabled services (ITES) industry, I find that competitive intensity positively moderates the relationship between firm resources and firm performance such that the relationships become stronger when competitive intensity is high than when it is low. Results imply that top managers' evaluation of the performance implications of internal firm resources are significantly shaped by the perceptions of intensity of competition encountered by their firms. © 2013 Wiley Periodicals, Inc.
