Brochure Content (Text and Images)
A very basic intranet without a large budget or significant requirements can be quite simple, yet still elegant and useful. If a company just wants to make a limited amount of textual and graphical information available to employees, then this approach can be sufficient. Including links to a public site and other resources is a good way to make this content compelling.
Some companies go forward with this type of idea to begin with. These cases will include information about lines of business, products, services, business hierarchy and internal policies. As it grows, however, it will typically become difficult to maintain. This is where Content Management Systems and dynamic templating systems become valuable.
Note that a large intranet site with informational utility and no interactivity can be created from brochure content, but the perception may be that it doesn't "DO" anything or that it is just marketing fluff. In addition, long-term maintenance of this content will be difficult.
