Boyd's Decision (OODA) Cycle

Diagram of Boyd's Decision (OODA) Cycle

The above diagram is what is know as the decision cycle, the Boyd cycle, the OODA loop, or the OODA cycle; an important concept used in business and military strategy. John Boyd, who developed the cycle, saw decision making as occurring in a series of observe-orient-decide-act cycles. When one processes this cycle quickly and can get inside an opponent's decision cycle, one may gain an advantage. This cycle may also be applied to personal self-defense situations.
