Prototype
Prototype the flow before production
- Sketches are enough for early structure questions.
- Click-through prototypes help test screen order and comprehension.
- Code prototypes can test realistic branching and assistive technology behavior.
Weak versus strong

Weak
Final visual quality.
Strong
Does the flow make sense?
Click-through
Weak
Real backend behavior.
Strong
Can users move through the screens?
Code prototype
Weak
Production readiness.
Strong
Does branching, device behavior, or accessibility need realism?
