Before examining the sources of information, and how to improve each of them, one must first devise a model of how human decisions are made. U.S. Air Force Colonel John Boyd devised a prescient model he called the “OODA Loop” (USMC, 1992). The principle was that a person Observes a situation, then Orients himself, Decides on a course of action, and then Acts to carry it out. Per his theory, this cycle repeats continuously, according to the speed and dynamics of a changing environment. The OODA Loop concept was initially oriented towards warfare, but it has universal application in life. Every human, when faced with a dynamic situation, will follow those steps: Observe, Orient, Decide, and Act. This “OODA Loop” can also be considered a “Decision-Making Cycle” (Hammonds, 2002).
