“Generating a rapidly changing environment—that is, engaging in activity that is so quick it is disorienting and appears uncertain or ambiguous to the enemy—inhibits the adversary’s ability to adapt and causes confusion and disorder that, in turn, causes an adversary to overreact or underreact. Boyd closed the briefing by saying the message is that whoever can handle the quickest rate of change is the one who survives.”
― Robert Coram, Boyd: The Fighter Pilot Who Changed the Art of War

“They usually did not fight what is known as a “war of attrition.â€� Rather, they used deception, speed, fluidity of action, and strength against weakness. They used tactics that disoriented and confused—tactics that, in Boyd’s words, caused the enemy “to unravel before the fight.”

“The briefing begins with what was to become Boyd’s most famous—and least understood—legacy: the Observe-Orient-Decide-Act cycle, or O-O-D-A Loop. Today, anyone can hook up to an Internet browser, type “OODA Loop,â€� and find more than one thousand references. The phrase has become a buzz word in the military and among business consultants who preach a time-based strategy. But few of those who speak so glibly about the OODA Loop have a true understanding of what it means and what it can do. (Boyd preferred “O-O-D-A Loopâ€� but soon gave up and accepted “OODAâ€� because most people wrote it that way.)”

“For a time, Boyd and Spinney were reluctant to fully explain the OODA Loop; it was far too dangerous. If someone truly understands how to create menace and uncertainty and mistrust, then how to exploit and magnify the presence of these disconcerting elements, the Loop can be vicious, a terribly destructive force, virtually unstoppable in causing panic and confusion and—Boyd’s phrase is best—“unraveling the competition.â€� This is true whether the Loop is applied in combat, in competitive business practices, in sports, or in personal relationships. The most amazing aspect of the OODA Loop is that the losing side rarely understands what happened.”
― Robert Coram, Boyd: The Fighter Pilot Who Changed the Art of War

“The OODA Loop is often seen as a simple one-dimensional cycle, where one observes what the enemy is doing, becomes oriented to the enemy action, makes a decision, and then takes an action. This “dumbing downâ€� of a highly complex concept is especially prevalent in the military, where only the explicit part of the Loop is understood. The military believes speed is the most important element of the cycle, that whoever can go through the cycle the fastest will prevail. It is true that speed is crucial, but not the speed of simply cycling through the Loop. By simplifying the cycle in this way, the military can make computer models. But computer models do not take into account the single most important part of the cycle—the orientation phase, especially the implicit part of the orientation phase.”

“Implicit Guidance & Controlâ€� from “Orientationâ€� with both “Observationsâ€� and “Action.â€� This is his way of pointing out that when one has developed the proper Fingerspitzengefuhl for a changing situation, the tempo picks up and it seems one is then able to bypass the explicit “Orientationâ€� and “Decisionâ€� part of the loop, to “Observeâ€� and “Actâ€� almost simultaneously. The speed must come from a deep intuitive understanding of one’s relationship to the rapidly changing environment. This is what enables a commander seemingly to bypass parts of the loop. It is this adaptability that gives the OODA Loop its awesome power. Understanding the OODA Loop enables a commander to compress time—that is, the time between observing a situation and taking an action.”

“Here Boyd says that to shape the environment, one must manifest four qualities: variety, rapidity, harmony, and initiative. A commander must have a series of responses that can be applied rapidly; he must harmonize his efforts and never be passive. To understand the briefing, one must keep these four qualities in mind.”
― Robert Coram, Boyd: The Fighter Pilot Who Changed the Art of War

“Another important slide shows how the Blitzkrieg—or maneuver conflict—is the perfect tactical application of the OODA Loop. Boyd asks: How does a commander harmonize the numerous individual thrusts of a Blitzkrieg attack and maintain the cohesion of his larger effort? The answer is that the Blitzkrieg is far more than the lightning thrusts that most people think of when they hear the term; rather it was all about high operational tempo and the rapid exploitation of opportunity. In a Blitzkrieg situation, the commander is able to maintain a high operational tempo and rapidly exploit opportunity because he makes sure his subordinates know his intent, his Schwerpunkt. They are not micromanaged, that is, they are not told to seize and hold a certain hill; instead they are given “mission orders.â€� This means that they understand their commander’s overall intent and they know their job is to do whatever is necessary to fulfill that intent. The subordinate and the commander share a common outlook. They trust each other, and this trust is the glue that holds the apparently formless effort together. Trust emphasizes implicit over explicit communications. Trust is the unifying concept. This gives the subordinate great freedom of action. Trust is an example of a moral force that helps bind groups together in what Boyd called an “organic whole.”

“Boyd dove deeper and deeper into the study of war. He realized that while wars take place between nations, every person experiences some form of war; conflict is a fundamental part of human nature. To prevail in personal and business relations, and especially war, we must understand what takes place in a person’s mind.”
