I had a disheartening discussion with a programmer at our office yesterday. He felt that we should not "waste our time" with prototypes, or even wireframes! He said that our creative director found the wireframes limiting, and ended up giving back to us exactly the layout that was provided in the wireframes. I explained that the process of wireframing and prototyping helps work out the flow of content, the page requirements, online interactions, and serves as a guide for design. And I said that many designers I'd worked with had been able to interpret the wireframes just fine.
