STORY & REFLECTION
Feedback about a sticking zipper
Guidance-based illustration · Feedback about a sticking zipper
Illustrative scene: A bag shop gets many “beautiful” reviews. One returning buyer mentions a hard-to-open zipper, a detail the owner had treated as too minor to investigate.
She asks a few buyers where it catches, tries opening it one-handed, and finds fabric snagging the teeth. She adjusts the next pattern and asks again after use.
The SBA recommends using customer behavior and market trends to test a business idea, alongside competitor research. Evidence from actual customers can guide the next question.
Praise encourages; usable details improve the product.
