Pretotyping

Make sure you are building the right thing before you build it right....

This I would say, is the thing that skilled industrial, product, interaction, service- designers do. It might not be called pretotyping, but it is part of the design process. It is divergent processes feeding into convergence processes that ensure that a successful solution will come out. And what kind of perspectives, studies, data, trends that you add in that first phase will affect the result.
