Great question. ASAP is one of those dangerous phrases that should be used with caution. It never be used with anyone "higher" in status. I.e. never say to your supervisor or boss: Please do this ASAP. And if you are a good boss or supervisor, don't use it with your employees! It usually comes across as mildly rude. You can use it as an inclusive again with caution. "Team members, we have this important request. Can we get this done ASAP? Thanks." In speech it can be even ruder! "Fred, I need this ASAP" is fine if you and Fred are equals and friends. Otherwise, it's pushy.
