For many organizations effective supplier evaluation and purchasing processes are of vital impor-tance. As the pace of market globalization quickens, the number of potential suppliers and the number of factors to consider when selecting suppliers increases. In this paper we present the crit-ical success factors (CSFs) for supplier selection reported in the literature emanating from the seminal work of Dickson and provide an update based on reviewing more than 110 research pa-pers. Our study indicates significant change in the relative importance of various critical success factors in the research reported during 1966-1990 versus 1990-2001. Increased competition and globalization of markets facilitated by Internet-based technologies have combined to dramatically change the ranking of factors while introducing new criteria to the supplier selection process. Based on the results of this study, we conclude that supplier selection criteria will continue to change based on an expanded definition of excellence to include traditional aspects of perfor-mance (quality, delivery, price, service) in addition to non-traditional, evolving ones (just-in-time communication, process improvement, supply chain management)
