Purple Question

I just finished Purple Cow. In the book, Seth Godin asks one very intelligent question a number of different ways.

What are you doing to create a remarkable experience for the person who will consume your product?

The foundation Godin uses to answer this question is a mixture of anecdotal evidence and rational thought. The choice of case studies and source material makes the answers compelling narratively but prone to criticism from a scientific standpoint, similar to the work of Malcolm Gladwell. I do feel, however, that the question is an interesting litmus test for the work that I do as an application developer. It works in interviews, in code reviews, in strategy meetings, everywhere. It's rare that a single question can cut to the chase like that and cross domains with ease. Pretty awesome.
