The article discusses the importance of prototyping in the design process, emphasizing how it enables rapid iteration and effective communication of ideas. It outlines various prototyping methods and tools, highlighting their roles in enhancing creativity and problem-solving in product development.

Designers are often relegated to a role of mere decoration in the software development process, where their authority is undermined by the tools and practices that separate design from implementation. To reclaim their role and influence, designers should engage directly with the execution of their ideas by using platforms that allow them to build and ship products. By doing so, they can close the feedback loop and return to true design work.
