This document summarizes a study on the adoption of e-procurement technologies by companies. The study found that while companies expected to rapidly adopt these technologies in the late 1990s, actual adoption has been much slower. Most companies are experimentally using e-procurement on a small scale and waiting to see how uncertainties are resolved before fully adopting the technologies. The document also outlines the main types of e-procurement technologies and how adoption strategies have ranged from aggressive experimentation to more conservative selective use.
