Part 3: Decide

John Boyd developed his ideas during his own time as a fighter pilot. He earned the nickname “Forty-Second Boyd” for his ability to win any fight in under 40 seconds.

 Boyd spent his career observing people and organizations. How do they adapt to changeable environments in ...

The first step in the OODA Loop is to observe. At this stage, the main focus is to build a comprehensive picture of the situation with as much accuracy as possible.

A fighter pilot needs to consider: What is immediately affecting me? What is affecting my opponent? What could affect us later...

Orientation is frequently misunderstood or skipped because it is less intuitive than the other stages. Boyd referred to it as the schwerpunkt, a German term that loosely translates to “the main emphasis.” In this context, to orient is to recognize the barriers that might interfere with the other ...

In a closed system, entropy always increases and everything moves towards chaos. Energy spreads out and becomes disorganized.

A  fighter pilot must be an open system or they will fail. They must draw “energy” (information) from outside them...

Ideas should be tested and then, if necessary, discarded.

OODA is a feedback loop, with the outcome of actions leading back to observations. 

We can incorporate testing into our decision-making processes by keeping track of outcomes in 

Uncertainty does not always equate to risk. A fighter pilot is in a precarious situation, where there will be gaps in their knowledge. They cannot read the mind of the opponent and might have incomplete information about the weather conditions and surrounding environment. They can, however, take ...

OODA stands for Observe, Orient, Decide, Act. The description of it as a loop is crucial. Boyd intended the four steps to be repeated again and again until a conflict finishes. Although most depictions of the OODA loop portray it as a superficial idea, there is a lot of depth to it. Using it shou...

Four main barriers prevent us from seeing information in an unbiased manner:

• Our cultural traditions.
• Our genetic heritage.
• Our ability to analyze and synthesize.
• The influx of new information — it is hard to make sense of observations when the situation keeps c...

While technically a decision-making process, the OODA loop is all about action. The ability to act upon rational decisions is a serious advantage.

The other steps are mere precursors. A decision made, now is the time to act upon it. Also known as the test stage, this is when we experiment t...

Fighter pilots must make many decisions in fast succession. They don’t have time to list pros and cons or to consider every available avenue. Once the OODA loop becomes part of their mental toolboxes, they should be able to cycle through it in a matter of seconds.

Speed is a crucial element...

Gödel’s theorems indicate that any mental model we have of reality will omit certain information and that Bayesian updating must be used to bring it in line with reality. Our understanding of science illustrates this.

In the past, people’s conception of reality missed crucial concepts such ...

• Military leaders and strategists invest a great deal of time in developing and teaching decision-making processes.
• Developed by strategist and U.S. Air Force Colonel John Boyd, the OODA loop is a practical concept designed to be the foundation of rational thinking in confusing or cha...

Using the OODA loop should enable us to act faster than an opponent, thereby seeming unpredictable. While they are still deciding what to do, we have already acted. This resets their own loop, moving them back to the observation stage. Keep doing this, and they are either rendered immobile or for...

This principle describes the limit of the precision with which pairs of physical properties can be understood.

We cannot know the position and the velocity of a body at the same time. We can know either its location or its speed, but not both. 

If a pilot focuses too hard on where a...
