OODA

OODA (Observe, Orient, Decide, Act) is a cyclical decision model from strategist John Boyd, originally designed for aerial combat. You observe the environment, orient by interpreting what you see in context, decide what to do, act — and loop. In AI agents it maps cleanly onto: gather data through tools, analyze with an LLM, plan the next step, execute, repeat. The core insight is speed: whichever side cycles faster forces the other to react to stale information. Pairs well with ReAct and system thinking.
