When in fact these things, and 100 other goals and considerations like being green or hiring fairly or paying interns better etc... merely influence each other a little and don't preclude each other except at absurd hyperbolic extremes.
The different goals DO influence each other. But the output product can in fact have a whole bunch of both speed and reliability, probably at the expense of yet another dimension like cost, but actually the same applies there too, you can possibly have all 3, at least to some degree, if the leadership is insightful enough to figure out a way like employing underutilized people or geography, or gamification or crowdsourcing or alternative incentives, whatever.
Pay more or sacrifice in one dimension to get more in another is merely the obvious and easy way, not the only way dictated by some zero sum law of conservation.
