Whatever you first create has some kind of vision behind it. Even if that vision is a rough spec, it might be precisely the little bit of spec that’s necessary to get things started. A good requirements spec doesn’t mean it has to be heavyweight with all the corners and edges figured out. Instead, it can be just lightweight enough to get things moving in the proper direction... but some little direction is certainly needed.
