Creating SV-10 System Activity Sequence and Timing descriptions
Three types of models are needed to refine and extend the systems view of an architecture to adequately describe the dynamic behavior and performance characteristics of an architecture.
The following three models are used to refine the descriptions:
•Systems Rules Model (SV-10a)
•Systems State Transition Description (SV-10b)
•Systems Event/Trace Description (SV-10c)
The Systems State Transition Description and Systems Event/Trace Description can be used separately or together, as necessary to depict the timing and sequencing behavior in the systems architecture view. Both of these diagrams describe systems responses to sequences of events. When an event occurs, the action to be taken can be subject to a rule or set of rules as described in the Systems Rule Model.
