Projects without a concept and some thought toward regularly checking the status of things are chaotic. Chaos has no goal. You can establish a goal and ride the wind, but it is very difficult to constantly keep the wind under control. The result of chaos is serendipitous results or more chaos. The odds of chaos being a straight line toward an acceptable goal are in the realm of practical improbability.
Stories are in highly competitive markets.
I would not want to begin ordering a story out of chaos and depend on serendipitous results. But there are some highly talented people who can. Process management always produces acceptable results. Process management 1 understands that as the project unfolds, new possibilities are revealed and some things don't work as planned. For example, I have a broad concept in mind of what I want to write.
