Disagree openly, then commit fully

Why this rule exists

A team where people nod along and then quietly withhold their effort is worse than one that argues, because the disagreement doesn't disappear; it just goes underground and comes out as passive resistance. Real debate before a decision surfaces the risks while they can still be addressed. But debate has to end somewhere, and once a decision is made, relitigating it forever paralyzes everyone. The discipline is two-sided: argue hard beforehand, then commit fully afterward, even to the choice you argued against. Both halves are required, and most teams skip one.
