Dennis Howlett reminds me that the last paragraph of my Naked Answers post suggests that I think the only way innovation happens is in reaction to customer demand. Customer feedback is an important ingredient, but not of course not the only component. Henri Fords famous quote “If I had asked people what they wanted, they would have said, "Faster horses.”" signifies that to make a real difference revolutionary thinking is required. I live on the balance of these two components every day.
