Product prototyping is the process of creating early models of a product to test its viability and gather user feedback before production, which helps identify potential issues and enhance customer satisfaction. Various types of prototypes, such as sketch, functional, and visual prototypes, are utilized to refine designs and assess marketability. The rise of technologies like AI, IoT, and 3D printing is transforming prototyping, making it more efficient and cost-effective, while also allowing for virtual evaluations.
