For Figure: Indicate the sequence of activities by putting numbers next to the data flows. For example, the Customer order in the upper left of the diagram would be number “1.” Restart the numbers for each bubble. Assign the same number to simultaneous data flows. For example, several different data flows coming out of bubble 3.0 should get the same number. 

For each process bubble, indicate, by placing a “T” on the flow, the flow that triggers the processing activities. 

Label each flow into and out of the data stores and to and from the other processes. These labels should describe the purpose of the flow. 

Annotate each data store to indicate the data’s major elements.

Include on the diagram one-sentence descriptions of each process bubble’s activities.
