Boyd's decision cycle: Observe, Orient, Decide, Act — faster cycling beats opponent.

John Boyd's decision cycle of Observe, Orient, Decide, Act describes how an agent processes information and acts in adversarial contexts. The framework's central claim is that operating inside an opponent's OODA loop — cycling faster while remaining accurate — produces decisive advantage by inducing confusion and paralysis. Boyd developed the framework during fighter pilot work in the 1950s-60s and progressively expanded it into a general theory of conflict applicable to military strategy, business competition, and individual decision-making.

Observe
Orient (the most weighted phase, encompassing cultural heritage, genetic heritage, prior experience, analysis/synthesis, new information)
Decide
Act
Implicit guidance and control loops

Primary use case

Adversarial decision-making in military operations, business competition, and any context requiring fast adaptive response.

Common criticisms

The 'faster loop wins' summary oversimplifies Boyd's emphasis on Orientation as the critical phase
popularized as a catchy diagram that misses the framework's depth
difficult to operationalize the Orient phase rigorously.
