  • Numbering the processes

Потому что DFD служит для изображения потока данных.
Для изображения потока управления используется другой вид диаграмм - flowchart.

A flow chart details the processes to follow. A DFD details the flow of data through a system.

In a flow chart, the arrows represent transfer of control (not data) between elements and the elements are instructions or decision (or I/O, etc).

In a DFD, the arrows are actually data transfer between the elements, which are themselves parts of a system.
