One quick followup:
I'd say that effectiveness and efficiency are equally important but need to
be traded off against one another.
While a really horrible design can be improved with respect to both, I
think there reaches a point where improving one without at least trying to
maintain the other leads to worse designs.
Hyper-efficient designs tend to be effective but only within very limited
regimes; that is, they're not robust. And if they're not robust, then it
seems to me that they're not particularly effective.
