There are two types of decisions. There are decisions that are irreversible and highly consequential; we call them one-way doors, or Type 2 decisions. They need to be made slowly and carefully. I often find myself at Amazon acting as the chief slowdown officer: “Whoa, I want to see that decision analyzed seventeen more ways because it’s highly consequential and irreversible.” The problem is that most decisions aren’t like that. Most decisions are two-way doors.
