The OODA Loop is a decision-making framework developed by military strategist John Boyd.

This framework is intended to be iterative: the results of each step feed back into the beginning of the loop, informing subsequent iterations. This enables continuous improvement and refinement of the decision-making process.

Steps

1. Observe: Gather information from your environment. Pay attention to changes, threats, and opportunities.
2. Orient: Analyze the information, interpret it based on your experience, culture, and mental models.
3. Decide: Choose a course of action based on your orientation.
4. Act: Implement your decision quickly and observe the results.

邊開火邊移動（Fire & Movement）

“You move towards the enemy while firing your weapon. The firing forces him to keep his head down so he can’t fire at you. The motion allows you to conquer territory and get closer to your enemy, where your shots are much more likely to hit their target. If you’re not moving, the enemy gets to decide what happens, which is not a good thing. If you’re not firing, the enemy will fire at you, pinning you down.” — Joel Spolsky

The OODA Loop applied under adversarial tempo:

• Firing manufactures observation — Acting forces the opponent to react, and their reaction is information you need to re-orient and could not have gathered by waiting.
• Moving keeps the initiative — If you’re not moving, the opponent gets to decide what happens next.
• Tempo, not force, is the advantage — You win by cycling Observe → Orient → Decide → Act faster than the opponent can respond, not by hitting harder.
