This paper gives an overview on PROMET I-NET - a project model for planning and implementing Intranets. It covers all phases of an Intranet project starting from the requirement analysis to the implementation and rollout of the system. Unlike existing approaches, PROMET I-NET not only deals with technical issues but contains strategic and organizational aspects as well. However, the project model does not replace existing development and integra- tion methods but rather embraces them into its frame- work. The model was developed in the context of a re- search project in cooperation with leading German and Swiss enterprises where it has been validated in several projects.
