“I define failure as an outcome that deviates from desired results, whether that be failing to win a hoped-for gold medal, an oil tanker spilling thousands of tons of raw oil into the ocean instead of arriving safely in a harbor, a start-up that dives downward, or overcooking the fish meant for dinner. In short, failure is a lack of success. Next, I define errors (synonymous with mistakes) as unintended deviations from prespecified standards, such as procedures, rules, or policies.”
