Tony Hi:

Few points you missed:

* Main purpose of a DFD: To guide the analyst through a logical, natural partitioning of a system (vs a forced, artificial partitioning)

* Data flow diagrams are just as appropriate for completely manual systems. they are NOT just for software system.

* Basic difference between DFD and BPM: DFD’s are to capture processes at higher levels of abstraction and can document non-sequential processes and their interrelationships.
