In security, the goal is for the good guys to be faster than the bad guys in every way. That is how we prevent violence and crime from happening, by making observations, making decisions and taking action faster than the criminal can. This concept of operational speed is often summed up with the guidance to execute the OODA loop more quickly than the insurgents, terrorists and criminals we are hunting. I’ve found that, while this advice to be faster has become fairly common, the understanding of how to actually speed up the OODA loop is not as well understood.
