What is a prototype in UX design?

A prototype in UX design serves as an early model that demonstrates functionality. It allows designers to visualize and test their ideas in a tangible form before full development. Prototypes can range in fidelity from low-fidelity sketches or wireframes to high-fidelity interactive models, facilitating user testing and feedback early in the design process. This approach helps identify any usability issues or areas for improvement, saving time and resources before creating the final product.

By engaging users with prototypes, designers can gather insights and refine their concepts based on real interactions. This iterative process is crucial in UX design as it ensures that the end product effectively meets user needs and expectations. Conversely, the other choices refer to distinct aspects of the design and evaluation processes rather than a prototype itself. For example, an analytical evaluation focuses on assessing a completed interface, while a finalized product indicates the end stage of the design process, and user research findings entail documenting insights rather than demonstrating functionality.
