Planning your intranet is an iteractive process in which you develop a prototype, test how it works, and get feedback from users. Then you redesign to elinimate the problems and rerun your tests. Part of planning involves figuring out how your Web server will operate within your organization’s network, which can access it, and whether users have adequate bandwidth to access it over the existing network. You can project loads on the servers but you’ll more than likely need to rework your numbers as the process continues and as you put your server into actual use.
