Key takeaways — Decisive
- ✓ Always generate at least three options — when leadership teams catch themselves debating only "yes or no," they have already lost the most important part of the decision.
- ✓ Run premortems before major commitments: imagine the decision has failed in two years and work backward to identify what would have caused it.
- ✓ Set tripwires in advance — predefined signals that trigger a forced re-evaluation, protecting you from the slow drift of sunk-cost thinking.
Key takeaways — The Mom Test
- ✓ Avoid Idea-First Questioning by focusing your customer interviews entirely on the prospect's current life and past behaviors, which are the only reliable predictors of future purchases.
- ✓ Identify and ignore Compliments and Generic Feedback, recognizing that polite encouragement is a 'false signal' that often leads to the development of unnecessary features.
- ✓ Secure Customer Commitment—such as a follow-up meeting or a pre-order—as the only valid proof that your strategic solution addresses a real and urgent organizational need.
