Sobre este título
Engineers couldn't prove danger, so managers launched anyway. Seven astronauts died when O-rings failed in freezing temperatures. Apply the lessons learned to help avoid future incidents.
Three Key Takeaways:
- Reverse the burden of proof: Require positive proof that something is safe before proceeding, rather than forcing engineers to prove it's unsafe.
- Simplify safety communication: Complex data failed to convince decision-makers, but a simple demonstration (O-ring in ice water) made the danger crystal clear.
- Protect technical authority: Engineers need more than just formal authority to stop unsafe operations — they need genuine psychological safety to exercise that power without career consequences.
