Extranets
In a comprehensive Web solution, Extranets perform a role that enables an organization to expand the way they do business with their customer, and to make a positive, professional impression at the same time.

Extranets do this by providing secure access to a Web site that allows access to:
   - Shared data, to include document collaboration
   - Common calendars & schedules
   - Posting of progress status
   - Inventory or order status

Progressive companies use Web technologies to share information with a select group:
   - Frequent or large customers
   - Sales managers or reps
   - Distribution channels
   - Business Partners
   - Affiliates

An Example:
A general contractor posts drawings, specifications, and schedules for the construction of an office complex. All approved vendors and subcontractors can view these documents and, in some instances, make changes. If the weather delays concrete curing, the revised schedule is automatically sent to all affected parties, who can reschedule their resources right away, lessening their losses and exposure.
