The OODA Loop

Posted on November 6, 2014 at 2:40 PM

Boyd's key concept was that of the decision cycle or OODA Loop, the process by which an entity (either an individual or an organization) reacts to an event. According to this idea, the key to victory is to be able to create situations wherein one can make appropriate decisions more quickly than one's opponent. The construct was originally a theory of achieving success in air-to-air combat, developed out of Boyd's Energy-Maneuverability theory and his observations on air combat between MiGs and F-86s in Korea. Harry Hillaker (chief designer of the F-16) said of the OODA theory, "Time is the dominant parameter. The pilot who goes through the OODA cycle in the shortest time prevails because his opponent is caught responding to situations that have already changed."

Boyd hypothesized that all intelligent organisms and organizations undergo a continuous cycle of interaction with their environment. Boyd breaks this cycle down to four interrelated and overlapping processes through which one cycles continuously:

• Observation: the collection of data by means of the senses

• Orientation: the analysis and synthesis of data to form one's current mental perspective

• Decision: the determination of a course of action based on one's current mental perspective

• Action: the physical playing-out of decisions


Of course, while this is taking place, the situation may be changing. It is sometimes necessary to cancel a planned action in order to meet the changes.

This decision cycle is thus known as the OODA loop. Boyd emphasized that this decision cycle is the central mechanism enabling adaptation (apart from natural selection) and is therefore critical to survival.

Boyd theorized that large organizations such as corporations, governments, or militaries possessed a hierarchy of OODA loops at tactical, grand-tactical (operational art), and strategic levels. In addition, he stated that most effective organizations have a highly decentralized chain of command that utilizes objective-driven orders, or directive control, rather than method-driven orders in order to harness the mental capacity and creative abilities of individual commanders at each level. In 2003, this power to the edge concept took the form of a DOD publication "Power to the Edge: the Information Age" by Dr. David S. Alberts and Richard E. Hayes. Boyd argued that such a structure creates a flexible "organic whole" that is quicker to adapt to rapidly changing situations. He noted, however, that any such highly decentralized organization would necessitate a high degree of mutual trust and a common outlook that came from prior shared experiences. Headquarters needs to know that the troops are perfectly capable of forming a good plan for taking a specific objective, and the troops need to know that Headquarters does not direct them to achieve certain objectives without good reason.

In 2007, strategy writer Robert Greene discussed the loop in a post called OODA and You. He insisted that it was "deeply relevant to any kind of competitive environment: business, politics,

sports, even the struggle of organisms to survive", and claimed to have been initially "struck by its brilliance".

[edit] Foundation of theories

Boyd never wrote a book on military strategy. The central works encompassing his theories on warfare consist of a several hundred slide presentation entitled Discourse on Winning & Losing and a short essay entitled Destruction & Creation (1976).

In Destruction & Creation, Boyd attempts to provide a philosophical foundation for his theories on warfare. In it he integrates Gödel's Incompleteness Theorem, Heisenberg's Uncertainty Principle, and the Second Law of Thermodynamics to provide a context and rationale for the development of the OODA Loop.

Boyd inferred the following from each of these theories:

• Gödel's Incompleteness Theorem: any logical model of reality is incomplete (and possibly inconsistent) and must be continuously refined/adapted in the face of new observations.

• Heisenberg's Uncertainty Principle: there is a limit on our ability to observe reality with precision.

• Second Law of Thermodynamics: The entropy of any closed system always tends to increase, and thus the nature of any given system is continuously changing even as efforts are directed toward maintaining it in its original form.


From this set of considerations, Boyd concluded that to maintain an accurate or effective grasp of reality one must undergo a continuous cycle of interaction with the environment geared to assessing its constant changes. Boyd, though he was hardly the first to do so, then expanded Darwin's theory of evolution, suggesting that natural selection applies not only in biological but also in social contexts (such as the survival of nations during war or businesses in free market competition). Integrating these two concepts, he stated that the decision cycle was the central mechanism of adaptation (in a social context) and that increasing one's own rate and accuracy of assessment vis-a-vis one's counterpart's rate and accuracy of assessment provides a substantial advantage in war or other forms of competition.
