John Boyd’s OODA loop (Observe, Orient, Decide, Act) was developed as a framework to help pilots make better decisions in battle. Since its inception in the 1970’s it has been adapted for other areas of operations, including business.
“Decision makers gather information (observe), form hypotheses about customer activity and the intentions of competitors (orient), make decisions, and act on them. The cycle is repeated continuously. The aggressive and conscious application of the process gives a business advantage over a competitor who is merely reacting to conditions as they occur or has poor awareness of the situation. Especially in business, in which teams of people are working the OODA Loop, it often gets stuck at the “D” (see Ullman) and no action is taken allowing the competition to gain the upper hand or resources to be wasted.” —Wikipedia
I came across the OODA Loop while in the military and have referred to it a few times, but it was not a major influence on my own thinking, or so I thought.
