8.3.2 
Identify functional behaviors
The functional behavior of the software product must be defined and associated 
with the measures of effectiveness and the previously defined operational threads. 
The operational behaviors should describe how the organizational elements interact 
with the software product by performing activities or workflows. The operational 
model should express the control logic to enforce business rules, policies, and pro-
cedures. The exchange of information among organizational elements should be 
expressed as inputs and outputs of an activity.
An operational model should be developed to depict the operational or business 
workflow associated with each scenario. During the development of the operational 
model, the systems that support the operational process should be identified as an 
actor. 
Figure 8.3
