No transcript. But I do this professionally all the time. Clients frequently come to me with a design in mind for a solution, and it's often important to back them up and get them to tell me what the problem actually is.

Usually, I start with the question "How would you be able to tell that this problem had been solved?" and repeat it two or twenty times in different words until someone actually tries to answer it.

On one occasion I handed a client my pen and asked whether it was a solution to their problem. They looked at me funny and said it wasn't. I asked them how they knew that, and after a while one of them said "well, for one thing, it doesn't do X" and I said "great!", took the pen back, and wrote "has to do X". Then I handed them the pen back and said "OK, suppose I add the ability to do X somehow to this pen. Is it a solution to your problem now?" and after a couple of iterations they got it and started actually telling me what their problem was.

The thing that used to astonish me is how often the proposed solution utterly fails to even address the problem articulated by the same person who proposed the solution. I've come to expect it.
