This paper traces the evolution of Internet-EDI technology in the last 3 years through two illustrative cases of it's implementation -an Internet-EDI pilot project by Bank of America (BofA) and Lawrence Livermore National Labs (LLNL) in 1994, and a robust, production level Internet-EDI implementation by McKesson in 1996. While BofA took a proof of concept approach in its early implementation, McKesson applied the traditional life cycle model in the system design and purchased much of its Internet-EDI capability up front, albeit at a prohibitive cost. The rapid evolution of the technology has resulted in the availability of browser-based systems in early 1997. By facilitating entry of small to mid size companies into EDI networks, these inexpensive systems could transform the competitive landscape within these networks
