"If it made sense..."

This is my all-time favorite New Yorker cartoon:

I imagine a lunchtime chat between scientists, one of whom discovered a clever solution to a research problem. He became so invested in his own idea that he lost sight of the problem itself. His colleague offered the cheeky comment in the caption as a reality check.

The scenario embodies a UX principle:

Don't pursue a solution until you've explored every aspect of the problem.

Solutions tend to be more relevant when they sprout from a well-researched issue. Starting with a solution and working backwards would be a powerful idea, too...if it made sense.
