What is the process of evaluating a prototype by observing real users to identify problems?

• A. Paper prototypes
• B. User testing
• C. Mock-up
• D. Wireframing

Answer: (B)

User testing is the process of evaluating a prototype by observing real users as they interact with it to identify problems. By watching people try to complete actual tasks, you see where the design confuses them, where steps are unclear, and where mistakes or slowdowns happen. This hands-on feedback helps you verify usability and spot improvements before moving to a more polished version. While other terms refer to specific kinds of representations—like a simple paper version, a static mock-up, or a basic wireframe—the key idea here is learning from real user interactions to improve the product.
