There are some who argue that the only test of progress is delivery and that the only thing which can be iterated is a live service. That is a horribly misguided approach. There is no point in producing a good answer to a bad question, and lots to be gained from investing time and energy in understanding the question before attempting to answer it. Even for pretty simple problems, badly formed initial questions can generate an endless – and expensive – chain of solutions which would never have needed to exist if that first question had been a better one. Characteristically, Paul Taylor asks some better questions about asking better questions.
