Over 80 per cent of Web application development is occurring on intranets. Intranets are private Web-based networks - internal Web sites - located within an organization's firewalls, that connect employees and business partners to corporate information. They are cheap, easy-to-use and because they are protected by corporate firewalls, IT managers don't have to worry too much about security issues. The value to companies is clear such as: easy access to sales and marketing information; human resource and employee benefits data; and updates on products information. This text provides an overview on how the reader can present the concepts of an Intranet to their company as a means to improve communications to their employees, customers, and vendors. The author addresses: what you can do with an Intranet; advantages and disadvantages of an Intranet; proposing a company Intranet with plans and budgets; case studies from Texas Instruments and other companies and the best and worst business practices for Intranet planning.
