3. Prototype Development and Testing

Prototype development and testing involve creating an early model of a product to evaluate its design and functionality. This process allows designers to visualize and refine ideas before full-scale production. During testing, users interact with the prototype to provide feedback on usability and performance. This feedback is crucial for identifying strengths and weaknesses, enabling improvements. Ultimately, this iterative process helps ensure that the final product meets user needs and expectations, reducing the risk of costly changes after production begins.
