What does the term "prototype testing" refer to?

The term "prototype testing" specifically refers to the process of evaluating a model to collect data and refine designs. In engineering and product development, a prototype serves as a preliminary version of a product that allows designers and engineers to test various aspects such as functionality, usability, and performance. By conducting tests on the prototype, stakeholders can gather important feedback and identify areas for improvement, ensuring that the final product meets the desired specifications and user needs. This iterative process is crucial because it helps in making informed decisions about design modifications, ultimately resulting in a more successful and effective end product.
