Architecture
Interactive information architecture organizes site content and functionality so that it aligns with the mission of site sponsors and the goals of site users. It also means planning for change and growth over time.
Architecture maps meaningful connections between chunks of content.
The interaction designer should be the ultimate owner of product quality. The most suitable would be someone without an interest in the construction of the product, and with the detachment to put himself in the user's place.
Understand the Client
Ask the Questions: What are our Goals and Tasks? How do we get there? Who are the players? What's the story?
Map & Identify
Organize it: What we have now. Where it is. Clean it up.
Solutions
Show the way: The Vision Thing. Models. Helpfulness. Styling.
Information Architecture begets Interaction Design
