Use existing UI patterns (like a standard "Save" button location) so users don't have to relearn your app. 🧪 Phase 4: Validate (Testing)
Ask "why" five times to get to the root cause of the problem.
Ensure the feature is usable for people with visual or motor impairments.
Testing reveals "blind spots" that the product team might have missed.
Determine how you will measure if the feature works (e.g., faster task completion, fewer support tickets). 🗺️ Phase 2: Map the Journey (Ideation) UX is about the flow, not just the single screen or button.
