OODA Loop, a sophisticated decision-making framework designed for high-stress environments such as military operations, law enforcement, and emergency medicine. Rather than being a simple linear checklist, this model functions as a dynamic, repeating cycle of observing surroundings, orienting to information, deciding on a path, and acting to test that hypothesis. The author emphasizes that orientation is the most critical phase because it involves interpreting raw data through mental models, prior experience, and cultural context. Effective use of this system requires adaptive performance and the ability to update one's understanding of reality faster than a situation evolves.https://valortec.com/ooda-loop-decision-making-under-stress/
