Fantastic post. Thank you. Whether it is the DSM Qor something else, we have to construct it from our observations and experience. There is no single unique way to do that. These things always involve disputes, compromise, and politics. We make this effort even when we know the outcome will be imperfect. We need things like the DSM so that we can communicate with each other. There will never be a final, complete, unchanging DSM. We change, the world changes, and our conclusions change.
