The Two-Way Door

Distinguishing reversible from irreversible decisions so you can move at the right speed on each

What is Bezos’s two-way door principle and how does it speed up decisions?

Jeff Bezos's two-way door framework distinguishes reversible decisions (two-way doors — go through and come back if you need to) from irreversible ones (one-way doors — once through, you cannot return). The rule is to move fast on two-way doors and deliberate carefully on one-way doors, rather than applying the same slow process to every decision.

In Amazon's 2015 shareholder letter, Jeff Bezos described how organizations slow down by treating every decision as if it required the same heavyweight process — when most decisions are reversible and only a few are not. Two-way doors can be walked back through. One-way doors cannot. The error of treating a two-way door as a one-way door is expensive (paralysis, slowness, missed opportunities). The error of treating a one-way door as a two-way door is also expensive (irreversible regret). The skill is telling them apart. Here are the practices that make the framework operational, with honest evidence.
