As a designer (ID) I began at first to think of this article as a forthright effort to compare and explain the two disciplines. However, it is clear the author has no idea what Industrial design is or it's role in the entire process. I work with DE's and in my experience they do not sit around and wait for me to throw something pretty or stylish or shiny over the wall so that they can make it work. Indeed, if that were true I'd be unemployed!
(ID) and (DE) work as a team. I will concede there are people who call themselves "Industrial designers" but then ignore the issues of manufacturing and/or usability; they are not constrained those issues and thereby are "artists". They misrepresent the discipline in my opinion.
What really confirms my assertion is this statement "My job is to design a working product and send that to an industrial designer to dress it up". So typical of engineering professionals who do not possess an accurate understanding of Industrial design. A good Industrial designer is excellent in his discipline AND has enough competency to understand the concerns of the design engineer (and vise versa) thereby "streamlining" the process, and hopefully reducing costs to the client. At this point the "blurring" of the two disciplines occur.
