The document discusses striking a balance between navigation and search when organizing information. It recommends:
1. Developing a taxonomy to categorize information into a hierarchical structure based on subject, type, or other facets. This taxonomy can then be applied in a system like SharePoint.
2. Using the taxonomy for both navigation, where users can browse categories, and search, where search results are structured according to the taxonomy.
3. Maintaining the taxonomy over time through an incremental process that engages users and keeps the structure consistent, easy to use, and aligned with how users think about information.
