OODA Loop Core rule: For reversible moves under time pressure, act on 70% confidence, then immediately re-observe. Cycle faster than the situation compounds; a late perfect plan loses to a fast loop. When to Use - Incident response, outage, or ongoing degradation where state is still moving. - Debugging a moving target (intermittent failure, live traffic shift). - Any time-bounded decision where waiting for full certainty costs more than a reversible action. When NOT to Use - The situation is static and you have time — deliberate analysis or a hypothesis differential wins. - The next action i…
