The article goes on about how this was a "thinking outside of the box" move and how it illustrates Kim's brilliance.
I don't know Kim's work. I'm going to assume that he's a talented guy, and perhaps the criticism that follows is better suited for the author, who chose to include it in the article. But this particular anecdote screams "fail!" to me, for one single reason: he was tasked with coming up a popsicle redesign. That was his deliverable, and his instructor was his client.
If I ask a designer to come up with a new design for the rainboots I'll be manufacturing, I don't want them to tell me how I can manufacture umbrellas or inform my customers about the weather so they don't need rainboots -- unless I've included that possibility in the scope of my request.
