For me the paper would have to be very stretchy, I tend to go back and insert stuff. But ... years ago I had the privilege of working with one of the most awesome designer/programmers I've ever met. We would argue and sketch away in a meeting room with huge whiteboards on three walls. When we were in agreement we would go off and code and document the stuff, wiping off the parts as we completed them. When the whiteboard was cleared, we were done with that module/class, whatever. Then we'd attack the next module. Wrote an all-of-business custom app (think ERP++) for our client in about three months. Don't think we could have done that with paper.
