subprocess

A process that is part of a larger process. (See also “process,” “process description,” and “process element.”)

A subprocess may or may not be further decomposed into more granular subprocesses or process elements. The terms “process,” “subprocess,” and “process element” form a hierarchy with “process” as the highest, most general term, “subprocesses” below it, and “process element” as the most specific. A subprocess can also be called a process element if it is not decomposed into further subprocesses.
