Federal Reserve Chairman Alan Greenspan was recently quoted as saying that information technology has begun to alter, fundamentally, the manner in which we do business and create economic value. In the information age, the organizations that survive will be those which succeed in using computer-based information systems (IS's) to provide sustainable competitive advantage. "Competitive advantage" refers to the ability of an organization to provide products or services that are distinctive and more desirable that those provided by the competition. In a 1999 article, Service and Maddox proposed a measure of an organization's ability to use its information system for this purpose. This project extends the work of Service and Maddox. It describes a mail survey of information system managers that enables the researchers to calculate the information quotient for their organizations. These measures are used to validate the theory proposed by Service and Maddox.
