Extranets are an emerging interorganizational system (IOS) that is expected to surpass EDI in electronic commerce volume. Although extranets appear to have great potential for business use, they have received little attention in academic research. They offer free form text, graphics, sound and video, greater communication functionality, low technical requirements and relatively low adoption costs in comparison to other types of IOS. Except for security issues, such as encryption the technology is readily available for large and small organizations around the world. This paper focuses on Extranets, but provides an overall typology of web based and EDI systems. Prior electronic commerce literature is analyzed and compared to extranet technology. The unique characteristics of global extranets provide international research opportunities in the areas of system benefits, type of information exchanged, level of partnership system access, antecedents for adoption, and emerging forms of IOS partnerships.
