OODA Loop
The OODA Loop is a decision-making framework developed by U.S. Air Force Colonel John Boyd that describes the cognitive cycle of effective action under uncertainty and competition: Observe (gather information), Orient (synthesize and interpret), Decide (choose a course of action), and Act (execute). Boyd's insight was that the speed of cycling through this loop — not raw capability — determines competitive advantage. The competitor who completes OODA cycles faster can act inside the opponent's decision cycle, creating confusion and overwhelming adaptive capacity.
