IA and agility

Brian Dillard, Monday, December 24, 2007 @ 5:30 am

A friend of mine recently left a position at a supposedly Agile shop where developers wrote code based on raw requirements rather than formal IA. When he described their process to me, I really felt his pain. I can't imagine trying to capture the complex requirements of Ajax applications without the tools of modern IA.

Good information architecture provides not only detailed blueprints for developers, but also the raw material for test cases. If your only documentation of a component is just a high-level business document or a working example of that component, then it's difficult to identify deviations from the spec or prove that an unexpected behavior is a bug. Sure, on Agile projects the first-round IA sometimes gets reverse-engineered from working demo code. But IA and UxD should be a central component of Agile development.
