Van Halen used to insist on a bowl of M&Ms with all the brown sweets removed as part of their rider. It’s a story often used to illustrate what absurd primadonnas they were, usually as a precursor to Dave Lee Roth smashing something up if the request wasn’t complied with.
It’s probably not the first thing that comes to mind as an example of design thinking.
According to Dave Lee Roth himself, there was method in their madness. Van Halen’s staging was huge, complex, and unusual. The demand for “M&M’s (WARNING: ABSOLUTELY NO BROWN ONES)” appeared towards the end of a multi-page contract specifying the exact technical requirements of their stage show.
It was there as a test.
If the band arrived to discover brown M&Ms, they knew that their contract hadn’t been read properly. What else might have been missed? Were the girders strong enough? Was the floor? If the brown M&Ms were there, then there was a good chance some important, and potentially dangerous, technical errors were too.
It’s a great example of design thinking because it combines an understanding of human psychology (people are too lazy to read the contract) with an innovative solution. It’s simple, pragmatic, and effective.
