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.
