Since the U.S. Department of Defense initiated the development of networked computers in 1969, Internet technologies have rapidly advanced and revolutionized the way we communicate and conduct business. The second wave of the technological revolution came with intranet technology in the mid-1990s. With the intranet, organizations have strengthened the powers and speed of data gathering and sharing, communication, collaboration, and decision making within a firewall-protected organizational boundary. The third wave of this technological evolution, extranets, began in the second half of the 1990s. Many believe that it is the key technology enabler that is triggering a revolution in the structure and operations of many organizations in the new Internet-driven global economy. In addition to maturing Internet technologies, several technology drivers, as well as business drivers, further pushed the emergence of new types of organizations--virtual corporations, virtual organizations, extended enterprises, and trans-enterprise systems.
