What advantage does rapid prototyping provide in the design process?

Rapid prototyping significantly enhances the design process by enabling quick iteration and testing of designs. This method allows designers to create physical representations of their ideas swiftly, which can be evaluated and refined based on testing and feedback. The ability to produce multiple iterations in a short time frame means that designers can explore various concepts and solutions effectively. This iterative process is crucial, as it helps identify flaws or areas for improvement early in development, ultimately leading to more effective and user-centered final products.

In contrast, other options suggest limitations that are contrary to the core purpose of rapid prototyping, such as reducing feedback opportunities or eliminating user input, which are essential for refining designs. Additionally, the assertion that prototypes cannot be changed undermines the very nature of rapid prototyping, which is designed for flexibility and adaptation.
