Score the current decision process (1-5 each):
| Dimension | Score | Signal |
|---|---|---|
| Problem clarity | _ /5 | Can you state the decision in one sentence? |
| Options explored | _ /5 | Have you considered 3+ alternatives including "do nothing"? |

| Type 1 (One-Way Door) | Type 2 (Two-Way Door) | |
|---|---|---|
| Reversibility | Irreversible or very costly to reverse | Easily reversible |

| Who decides | Senior person or group | Individual closest to the information |
| Time budget | Hours to weeks | Minutes to hours |
| Examples | Acquisition, firing someone, pricing model, market entry | Feature priority, tool selection, meeting format, hiring channel |
