Final answer:
A prototype is a preliminary model of a product or service created to gather feedback and test for potential issues, important in refining the detailed design.
Step-by-step explanation:
A prototype is a preliminary description of your product or service that is used to get feedback from experts in the industry and potential future customers. This definition aligns with the purpose of a prototype, which involves creating a trial working model of a design that is built to test design decisions and identify potential problems. During this stage, it is crucial to envision the future of the product, explain the need or purpose it fulfills, seek reviews and feedback on the design, and then refine the product based on the input received. This repetitive cycle of prototype creation, testing, and refinement is essential in the development of a detailed design that effectively addresses user needs and stands up to real-world conditions.
