What term describes early models used for testing product concepts?

The term that describes early models used for testing product concepts is "prototypes." Prototypes are functional representations or simulations of a product that allow designers and stakeholders to evaluate and test the feasibility, functionality, and usability of a concept before finalizing the design. They provide a practical way to visualize the product, making it easier to identify potential issues and gather feedback from users or team members.

Prototypes can range from simple sketches or models to more sophisticated versions using materials that simulate the final product. By testing these prototypes, entrepreneurs can refine their ideas, make necessary adjustments, and improve overall product design before moving into large-scale production or development. This iterative process is crucial in the product development lifecycle, as it helps minimize risks and enhances the chance of market success.
