Internet has made a spectacular impact on all organization, creating completely new challenges on one hand and on the other offering entirely new conveniences. Through the establishment of digital networks, a considerably faster and less expensive way is created to exchange information with others. Moreover spatiotemporal borders disappear. Hence, entirely new business models are being developed and companies are discovering completely new strategies to gain competitive advantage in this information age. Traditional economies defined by regions and countries have shifted to more globally orien

This study compares eBusiness capabilities of the forest products industries in the United States and Canada. Structural and functional factors limiting or encouraging eBusiness development, attitudes and perceived value of eBusiness, concerns and possible impacts of eBusiness on traditional business practices were studied. Results indicate that high potential exists for eBusiness to flourish in the forest products sectors in both these countries. However, the study indicated that Canadian respondents were further along in Internet implementation in 1998 relative to their U.S. counterparts. In

Increasingly ebusiness projects are undertaken by collaborations. Many collaborative ebusiness projects fail to achieve their stated objectives due partly to inadequate project management. Additional management functions result from the lack of central authority and the characteristics of the three levels involved in these projects: the participating organizations that voluntarily collaborate (a form of virtual organization) to achieve agreed ebusiness objectives; the project teams (normally operating as "virtual" teams); and representatives from participating organizations.

An increasing number of ebusiness projects are undertaken as voluntary collaborations of independent organizations. These projects are known as ‘ebusiness collaborative projects’. Industry sources estimate only about 20% of these projects achieve their stated objectives due partly to inadequate project management.
