OODA? Please explain for us civilian folk.
Wikipedia has a nice rundown, including a process chart.
It has become an important concept in business and military strategy. According to [creator] John Boyd, decision making occurs in a cycle of observe-orient-decide-act. An entity (either an individual or an organization) that can process this cycle quickly can get inside the opponent's decision cycle and gain a military or business advantage.
