There’s a saying often heard at Amazon: “Good intentions don’t work. Mechanisms do.” No company can rely on good intentions like “We must try harder!” or “Next time remember to…” to improve a process, solve a problem, or fix a mistake. That’s because people already had good intentions when the problems cropped up in the first place. Amazon realized early on that if you don’t change the underlying condition that created a problem, you should expect the problem to recur.
