A second skill set involves binding intranets to corporate IS systems , such as database, document management, facilities management, order processing, purchasing, inventory management and others. An intranet will not get far with just a Human Resources Web site and a few discussion groups that managers feel are a waste of employee time. Sometimes the business application will already exist but will require intranet access. In other cases, the VAR will have to develop the application as part of the intranet project. The third key skill is in the area of security .
Intranets deliver the most value when they successfully combine three classes of access.
First, open public access to product and service descriptions, press and investor relations material and other public information are a basic requirement for any enterprise wishing to realize the basic advantages of an Internet presence. Second, restricted public access is required for Internet users seeking specific services and information based on their unique relationships to the enterprise. These may be product owners needing service, vendors exchanging order information or customers seeking to execute a transaction. Each of these forms of access must be kept separate from the other. Third, restricted internal access is required for employees working on common projects or with common business units.
