A big fallacy seems to be that it is meaningful to just use existing data in whatever cruddy non-normalized form it comes in, and let the 'algorithms' sort it out. There needs to be strong mgmt support for getting outcomes, because the production team are going to have to change to support it, and they usually like doing things their own way. Typically, without analytics, sensible logging formats or a clue as to why the outside world behaves the way it does.
