One-Way vs. Two-Way Doors
Jeff Bezos stressed categorizing decisions as reversible or irreversible. In a message to his shareholders, he gave the analogy of one-way and two-way doors. With one-way doors, if you walk through them, you cannot get back to where you were before. These decisions are irreversible and must be well thought out. Two-way doors can be reopened if you've made a suboptimal choice. The bigger the decision, the more process we try to put into place for making it, causing slowness and unthoughtful risk aversion.
