How would you level a DFD?

Leveling is done by drawing a series of increasingly detailed diagrams until the desired degree of detail is reached. As shown in the Figure, DFD Leveling is first displaying the targeted system as a single process, and then showing more detail until all processes are functional primitives.

What are the six guidelines for drawing DFDs?

Guidelines for Drawing DFDs

Identify all net input and output data flows.

Work your way from inputs to outputs, backwards from outputs to inputs, or from the middle out.

Label all interface data flows carefully.

Label the bubbles in terms of their inputs and outputs.

Ignore initialization and termination.
