A direct process is one which has a causal agent and proceeds sequentially. Various aspects of a direct process are caused by interactions among the elements, which are dependent upon one another.

Cell division, which proceeds through three distinct phases, is an example of a direct scientific process. Each phase has a definite sequence through which it proceeds; events cannot occur until others are completed.
