What it is
Outlines sections, menus, and relationships between key areas of the app. Critical when product surface area has grown faster than the IA can support.
Concrete example
Site map diagram showing “Dashboard → Jobs → Job Detail → Invoices → Reports.”
When to use it
Pre-IA refactor, before adding a major new product surface, or when support tickets reveal users can't find existing features.
What Product Joi delivers
IA map: current state, proposed state, naming rationale, navigation patterns, and a migration plan with deprecation timeline.
