Four questions off one proposal, none of them from a template. aito.._predict role on assignments gives the role mix work of this type historically needed; _predict person per role ranks who actually does it. _predict success / on_time on projects reads delivery risk off the proposed shape. And _predict won on quotes answers the question the other tables structurally cannot — projects only contains work that was won, so the losses, and the objection behind each one, live only in the quote history.
