What does a usability prototype focus primarily on?

A usability prototype primarily focuses on the interaction of end users with the system. This type of prototype is designed to evaluate how real users engage with a product, assessing ease of use, intuitiveness, and the overall user experience. By simulating the functionality of the system, usability prototypes enable designers to gather feedback on how well users can navigate through the system, understand its features, and achieve their goals with minimal frustration.

This focus on user interaction is critical for refining user interfaces and ensuring that the final product meets user needs effectively. Through usability testing, designers can identify potential usability issues and make necessary adjustments before the final implementation.

Other aspects, such as technical specifications, data diagram designs, and quality standards, do not primarily address user interaction directly. While these elements are important in the broader context of a system's development, they do not capture the essential focus of usability prototypes, which is to enhance the user experience by prioritizing how users will interact with the system.
