Because intranets are built with standard components, many companies already have the necessary hardware and software. Whatever else the company needs to buy tends to be inexpensive, and Web browsers are already installed on many desktops. And of course, the existing network can be used to connect users to the servers. They just provide an easy access front-end for users. That can be done by simply attaching a Web server to applications and making them available to browsers that are already in use.
Departments maintain control.
The purchasing patterns of intranets are much like personal computers in the early days. Competitiveness is extremely important in business, and collaboration aids in competitiveness. The more employees save the results of their work so future projects can take advantage of it, the more effective the company will be. Documents in electronic form also facilitate collaboration because they are much more easily shared by project team members in different locations compared to paper reports. This enables teams to work much more effectively.
