I need a word or phrase, - noun or adjective, to describe an action/activity that's applied immediately following another action/activity, rather than in conjunction with the first operation. Let's call these actions/activities "frobbing" and "barring". So I want to refer to "barring right after frobbing" rather than "frobbing together with barring".
I was thinking of "compounded barring" or "aposteriori barring", but did not quite like those.
Edit: It is necessary that the phrase or word not refer to the frobbing, as I want to use the same phrase/word for multiple, different, initial actions (frobbing, bazzing, quuxing etc.)
