For most firms today, sustaining IT advantage will not come from whether you have the technology, but how effectively it is being used, which is expressed in the notions of IS effectiveness, IS success, or IS performance. It has been a continuing effort among IS researchers to search for organizational antecedents of higher IS performance. The current study uses discriminant analysis to analyze the empirical data from questionnaire survey of IS executives. Results show that the proposed set of organizational variables can be used to successfully distinguish between high and low IS performance. Implications of the results for organizations are also discussed.
