OODA Loop

OODA loop in business

“If you perceive faster, read the situation more accurately, decide and act, you shape events while the other side is still reacting to the last situation.”

OODA stands for four words: Observe, Orient, Decide, Act. You perceive what is happening.

Two circles of four arc segments lie side by side, and in each a dot runs around the circle: on the left a fast golden one, on the right a slow mist-blue one. Each time the golden dot reaches its Act field, a grid of dots in the middle shifts, and the slow dot aims at a spot that no longer exists. Then the image zooms into the Orient field: several rings lie there like lenses, and one distorted lens sends even the fast dot into empty space.
In short

If you perceive faster, read the situation more accurately, decide and act, you shape events while the other side is still reacting to the last situation.

What it’s about: OODA stands for four words: Observe, Orient, Decide, Act. You perceive what is happening. You interpret it in the light of your experience, your knowledge and your values. You make a decision and act on it. Your action changes the situation, so the cycle starts over at once. People, teams and organizations run through such loops all the time, usually without noticing.

The core messageCore statement and 3 clarifications
In essence

If you move through the cycle of perceiving, interpreting, deciding and acting faster and more accurately, you force the other side to react to a situation that has already passed.

It does not say
That rushing helps. What matters most is how you read the situation, not just how fast you are.
It does not say
That your action is good because it is fast. Speed is no measure of right and wrong.
It also says
In an organization, many loops run inside one another, and the slowest one often sets the pace.
The explanationSpeed alone is not enough.

Speed alone is not enough. Fast decisions based on a poor reading of the situation only lead you astray faster, and old assumptions, pride or fear distort what you see.

The question

How quickly and how accurately do you recognize what is changing right now?

The signs3 signs when you heed it · 3 when you overlook it
When you heed it
  • Days, not months, pass between feedback and your response.
  • You try new things in small steps before you commit in a big way.
  • You regularly ask which of your assumptions no longer hold.
When you overlook it
  • Your actions land in a situation that has already changed.
  • Decisions wait for the next scheduled meeting.
  • Or you keep making new decisions and hardly look at what is happening.

    Theory
    John Richard Boyd

    “Patterns of Conflict” (briefing, final version 1986): victory depends on getting inside the opponent’s cycle of observation, orientation, decision and action.

    Review
    Michael W. Hankins

    “Flying Camelot”: the OODA model is so vague that everyone sees in it what they want to see; it is one of many descriptions of intuitive learning and decision-making.

    Review
    Stephen Robinson

    “The Korean War and the OODA Loop: What Happened to the Kill Ratio?”: the 10-to-1 ratio does not stand up to scrutiny; more recent estimates are considerably lower and cite other reasons, such as pilot experience and equipment.

Where the research reaches its limits
  • The founding example is partly a myth: the 10-to-1 kill ratio in the Korean War does not hold up in more recent studies, and other factors played a part.
  • The model applies above all where opponents or markets react quickly.
  • In situations that call for patience, careful deliberation or reconciliation, speed can do harm.
  • The claim that the faster side shapes events comes from the model; it has not been measured.
Read more: what research shows

The model comes from John Richard Boyd, a fighter pilot and colonel in the U.S. Air Force. In his briefing “Patterns of Conflict,” whose final version dates from 1986, he describes success in conflict as the ability to get inside the opponent’s cycle of observation, orientation, decision and action. His ideas shaped the doctrine of maneuver warfare in the U.S. Marine Corps. John Richard Boyd based the model partly on the advantage of the F-86 in the Korean War; more recent analyses find the often-cited 10-to-1 kill ratio untenable and point to other reasons, such as the pilots’ experience. The aviation historian Michael W. Hankins considers the model so vague that supporters and critics alike see in it what they want to see; in his view, it is not wrong, but it is neither unique nor especially profound. The core statement has never been measured.

The action steps5 things you can actually do
  1. Shorten the path from feedback to decision: Who sees what is happening with your customers, in your team or in your family, and how quickly do you hear about it?

  2. Replace one big bet with several small experiments whose results you will see soon.

  3. Check your reading of the situation: Which assumption, what pride or what fear is coloring what you see right now? Get a second opinion.

  4. Look for the slowest loop in your area, often an approval or a report, and speed it up first.

  5. Commit as late as the situation allows and as early as it demands.

The reflection questions3 questions: In your area, how long does it take from an important piece of feedback to a decision?
  1. In your area, how long does it take from an important piece of feedback to a decision?
  2. Which of your assumptions about your customers, your team or your family have you not checked in a long time?
  3. Where are you reacting right now to a situation that no longer exists?

Take your time with one question. Write down your answer – or talk it over with someone you trust.

Shein and the OODA Loop

At times, the online fashion retailer Shein puts thousands of new items online every day, at first in runs of about 100 pieces. Whatever sells is reordered; everything else disappears again. Shein moves through the cycle of observing, interpreting, deciding and acting faster than almost any competitor, with all the consequences that follow.

James Carville, the War Room and the OODA Loop

In the 1992 presidential campaign, James Carville and George Stephanopoulos set up a “war room” for Bill Clinton in Little Rock. Its purpose: to answer every attack so quickly that the response still makes it into the same news cycle. The opponent is meant to be constantly reacting to a situation that has already changed again.

John Boyd, the F-86 and the OODA Loop

In the Korean War, the Soviet MiG-15 fighter outperforms the American F-86 Sabre in many respects. Even so, the Sabre pilots come off better. John Richard Boyd later explains this with faster perception and faster transitions, and out of this the OODA Loop is born. The explanation is influential, but not undisputed.

Movie: Top Gun

In Tony Scott’s 1986 film, the naval aviator Maverick learns at an elite school that in air combat, the winner is often the one who perceives and switches faster. But he also learns that speed without clear orientation and without regard for the team can be deadly.

FAQ

Questions about the OODA Loop

What does the OODA Loop say?

Every action follows a cycle of observing, orienting, deciding and acting. If you move through it faster and more accurately than the other side, you throw it off balance, because it is always reacting to a situation that has already passed.

Where does the OODA Loop come from?

It comes from John Richard Boyd, a fighter pilot and colonel in the U.S. Air Force. He developed it in the 1970s from his analysis of air combat in the Korean War and presented it above all in his briefing “Patterns of Conflict.”

What are some examples of the OODA Loop?

The fashion retailer Shein with its small production runs, the war room of the 1992 Clinton campaign and John Richard Boyd’s own analysis of the F-86 in the Korean War.

How well is the OODA Loop supported by research?

Evidence: weak – an influential model from briefings, never tested empirically; its founding example has been partly refuted, and historians consider it imprecise.
