A **two-way door** is reversible (walk back cheaply), so decide it fast, low, and light. A **one-way door** is hard or expensive to reverse, so give it real rigor and senior sign-off. The load-bearing move is separating the reversibility judgment from the decision itself, which routes scarce deliberation toward the irreversible few and licenses speed on the reversible many. The output is a **reversibility classification plus a matched deliberation level** - it says how much machinery the choice deserves, never which option to pick. ## When to Use - A decision is on the table and it is unclear how much process it deserves. - Someone is about to rubber-stamp something irreversible, or convene a committee over something trivially reversible. - A team or org is chronically slow, applying the same heavyweight approval to everything regardless of stakes. - You want an explicit, defensible reason - decided before deliberation starts - to either move fast or slow down. ## When NOT to Use - **When the decision is already known to be high-stakes and is being analyzed.** Triage already happened; you are past this tool. Use a risk tool (premortem) or a
