It's less clear that the situation is as dire if each level has metrics and can self-adjust to optimize its performance.
But these are inherently subjective things, what the "right idea" is, or the "right implementation" is all up in our head that we can try to verbalize, but I don't think you can come up with an objective score for it, ask 100 programmers you'll get 100 different answers what "clean design" is.
