I learned about the OODA loop in basic training. It's a useful concept.
Just to be clear, it does not mean that in the heat of a fight you have to be running down a little mental checklist "I've completed step 2, so now I'm on to step 3 where I get to decide." You run through the loop in a time scale appropriate to the situation, which could be months for a business campaign or a split second for a life and death physical confrontation.
I do think that people can and do miss out on the OODA loop in many real life situations, but as Chris notes, the results are likely to be bad.
If you fail to observe or orient, then you are acting without awareness or understanding of what is going on.
(Imagine a soon-to-be mugging victim who fails to notice a pair of potential assailants moving into position around him or who notices but fails to comprehend the threat.)
If you fail to decide, then you will typically keep moving along whatever path you were already on, whether or not that is appropriate to the situation.
If you fail to act (as often occurs when a victim of violence "freezes up"), then you are paralyzed.
If you fail to loop (i.e. continue the process) then you will be locked into whatever action you committed to initially, even though it may no longer be a wise course of action. (Imagine that you are beating the crap out of your initial assailant and fail to notice or react to the fact that his six buddies are coming up to help him out.)
When you see a situation that was handled disastrously, it's not that unusual to realize that someone missed one or more of the OODA loop steps.
In the case of a skilled professional dealing with a situation which requires split-second reactions (like a bouncer in a fight or a race car driver on the track) the loop may be largely subconscious, but it is still there.
