The Virtual Environment
• The virtual corporation’s dynamic global multienterprise
organization and team oriented collaborative approach to
work will place very stringent requirements on the venture’s
telecommunications network.
• Is critically dependent on the timely flow of accurate
information throughout the organization
• Must be capable of assembling its capabilities and resources
quickly, thereby bringing a product to the market swiftly
• Will possess a dynamic network organization, synthesizing
the best available design, production, supply and distribution
capabilities and resources from enterprises around the world
and link them and the virtual corporation’s customer together.
• Will enable the virtual corporation to respond to a competitive
opportunity quickly and with the requisite scale, while, at the
same time, enabling the individual network participant’s cost
and risk to be reduced.

computers tied together by means of high speed
communications lines to form an apparently
