It basically gives the decision making cycle in any situation
OODA stands for: - observe-orient-decide-act
So whoever completes this loop first has the ultimate advantage over its competitor.
The second O, orientation – as the repository of our genetic heritage, cultural tradition, and previous experiences – is the most important part of the O-O-D-A loop since it shapes the way we observe, the way we decide, the way we act.
The faster we operate and in a particular rhythm there is more chance of winning any combat may it is in a battlefield or the business.
