ranking :  Let's talk about metrics for a second. Suppose you're
in a war, and your metric for determining tactics is, how much
of your opponent's forces you can destroy for the least cost.
You drop an atomic bomb, and destroy huge numbers of your
opposing forces at very low cost. Your metric says, you have
succeeded. Then it's pointed out to you that you've also killed
untold numbers of civilians, poisoned the survivors and land
with radiation, and done harm to your reputation. But since the
latter parameters weren't measured by your original metric, you
can still claim that dropping the bomb was an overwhelming
success. If your metrics only measure one effect, and don't
measure other effects, then they're not complete.
