Final answer:
UX designers review prototypes to get a better idea of the final website or app, as prototypes are preliminary models that are closer to the final product and allow for iterative improvements based on feedback and testing.
Step-by-step explanation:
When UX designers and collaborators want a better idea of the final state of a website or app, they can review prototypes. Prototypes serve as a preliminary model or draft and are used to understand design characteristics and evaluate the quality of a design. Creating a prototype is a crucial step after developing a mockup or storyboard, and it involves iterating based on feedback. While wireframes, user personas, and user journeys are valuable tools in the UX design process, it is the prototype that provides a closer representation of what the final product will look like and how it will function.
Explore possibilities is a step in the design process used to understand a prototype's characteristics and the likely advantages and disadvantages. Feedback received from testing prototypes leads to refinement, ensuring the design meets the purpose, audience, and organizational principles.
