During the past two decades, both academic researchers and business managers have attempted to understand the ways through which information technology (IT) can create business advantages. In this paper, we present a model that tests the relationship between IT infrastructure, customer focus, and business advantages. Customer Focus has been categorized into: customer responsiveness and product/service innovation. The data for the study were obtained from 116 executives from a number of business organizations. IT infrastructure is found to have significant effect on customer responsiveness, but does not show any significant relationship with product/service innovation. IT infrastructure, customer responsiveness, and product/service innovation are found to be significantly related business advantages.
