1. Define top level categories ( level 1 navigation) in user terms, not in terms of the source of the content. This results in categories defined according to subject or purpose (user populations who have similar needs).
2. Ensure that clear mission statements exist for each : for example, this space provides these things for these people. Or even better, this space lets these people do A, B or C by providing them with X, Y Z.
3. Implement a double-ownership approach, with roles in charge of the spaces and thereby representing user needs, and other roles in charge of content, thereby ensure information and services of high quality and relevance.
4. Distinguish between content created "for us by us" and "for others by us". Departments and functions tend to want to put both in the same space on the intranet, and this is not logical for users.
