The crux of DTSTTCPW is defining the problem. It's difficult to work in the abstract if you don't have a very strong sense of what your goals are. You can see in the development of pipes that they had McIlroy's "Summary - what's most important" memo, probably a multitude of other such memos, a strong team and eight years. Most people have themselves, a couple of scratched notes and a few months... Getting lost in the dark abysses of the abstract in these circumstances is not fun. Suboptimal is your saviour, if not the world's.
