Task: Create Black Box Activity Diagrams
This task defines an activity diagram that describes the use case functional flow at the black-box level.
Disciplines: System Engineering Requirements

      Steps
      Review the requirements to identify required system functions
      Review the system requirements associated with the subject use case and identify the required coarse-grained system functions. Create action nodes on the activity diagram for each system function.
      Determine the sequencing of functions required
      Create control flows to sequence the system functions (actions) to generate the required behavior.
