What is the main benefit of using a usability prototype?

The main benefit of using a usability prototype is centered on gathering user feedback on system interaction. Usability prototypes are designed to simulate the user experience and allow users to interact with the system in a way that closely resembles the final product. Through this interaction, users can provide valuable insights about their experiences, preferences, and any challenges they encounter while navigating the interface.

This feedback is essential because it helps identify usability issues early in the design process, ensuring that the final product is user-friendly and meets user needs. By incorporating direct user feedback, teams can make informed design decisions, leading to a more effective and satisfying user experience once the system is deployed.

This approach contrasts with simply improving data structure understanding or ensuring accurate requirement specification, as those focus on the informational architecture or formal documentation rather than the hands-on experience of the user. Likewise, while demonstrating solution options can be beneficial, the primary strength of usability prototypes lies in their ability to capture real-time user interactions and feedback, which informs further development and refinement of the product.
