The solution was a broad, end-to-end usability check that tested the real connection journey before launch.¹

The test used twenty-three crowd-testers and asked them to search for both functional and usability issues.¹ Including testers with low to moderate interest in technology helped expose the camera-app connection problem in a broader usability context.¹

Most importantly, the method connected discovery to timing. Usability testing uncovered critical issues that would otherwise have gone unnoticed.¹ Errors found early are ten times cheaper to fix than later phase issues.¹ The practical pattern is straightforward: test the complete task, include a realistic range of confidence, and use the findings while change is still affordable.
