How does prototyping contribute to user engagement?

Prototyping contributes to user engagement primarily by allowing users to interact with a tangible version of the product. This interaction creates a hands-on experience that enhances user involvement and feedback during the product development process. When users can physically interact with a prototype, they can better understand the product’s functionality, identify areas for improvement, and express their needs and preferences. This involvement not only increases user satisfaction but also helps designers and developers create a product that genuinely resonates with the target audience.

The other options, while relevant to different aspects of product development, do not specifically focus on enhancing user engagement through interaction. For instance, minimizing manufacturing costs, streamlining supply chain processes, and simplifying design verification are valuable for efficiency and cost management, but they do not directly facilitate user interaction and involvement in the way that prototyping does.
