Overview: I was speaking to a client recently about there SharePoint Intranet and I mentioned they should have a Information Architecture (IA). This should preferably be done by an Information architect but at a minimum the organisation can get the IA from project stakeholders. Below I list the 2 most commonly found IA representations approaches: Wireframes & Hierarchy/structure diagrams.
What is IA?
Wikipedia define IA as "Information architecture is the categorization of information into a coherent structure, preferably one that most people can understand quickly, if not inherently. It's usually hierarchical, but can have other structures".
For web based projects, the best 2 methods for defining IA are a hierarchy and a wireframe other useful tools are defining the taxonomy against the hierarchy IA diagram. I have seen various techniques to achieve this but keeping it simple as listed below and having a separate annotated version defining the term set or formal business taxonomy at each level is useful.
