Real World Example
A government benefits portal is adding an online application form used by people with different devices, abilities, and assistive technologies.
The feature can pass functional tests while still blocking users who rely on keyboard navigation, screen readers, captions, or sufficient color contrast. Usability lab keeps that risk visible.
The tester checks the application path with assistive technology expectations in mind, including labels, focus order, error messages, and completion without a mouse.
The team releases a service that more citizens can actually use because Usability lab is treated as a product quality concern, not a cosmetic review.
