Atrocious article. “… needs to know how to draw as much as an electronic producer needs to know how to play the piano”
Not only as a business guy you know nothing about industrial design but you also know absolutely nothing about music production.
What you probably want to say is “how to develop services with a designer point of view as a business guy”.
Don’t worry, the design field always has its fads like this “new product design” you mention. It will die sooner than you think and then real designers will stay.
Don’t ditch your business diploma yet.
