Prototype Testing is a crucial phase in the product development process where a preliminary version of a product, known as a prototype, is evaluated. This testing helps identify design flaws, usability issues, and areas for improvement before the final product is manufactured. By gathering feedback from users, developers can make informed decisions to enhance the product's functionality and user experience. During prototype testing, various methods such as user interviews, surveys, and observation are employed to collect data. The insights gained from this testing phase guide the design team in refining the product, ensuring it meets user needs and expectations effectively.
