Identify control behaviors
The control behaviors must be identified to disclose the decision logic and crite-
ria that govern data processing control flows. Control behaviors must account for 
all possible conditions that may be encountered throughout a functional scenario. 
Control behaviors dictate which functional sequence will be enabled among the 
possible courses of action. For example, when a loan application is being evaluated 
by a bank officer, the loan may be approved, disapproved, or deferred until further 
information is provided. The operational or business model should have identified 
the business rules that guide this transaction. The control behaviors must identify 
how the software will interrogate data items to enforce the business rules.
The control behaviors represent the decision logic that must be captured at a 
detailed level so that the software development team understands the precise nature 
of how data processing control flow choices will be affected and the selection cri-
teria that govern which branch of functional execution to enable. The following are 
typical control logic constructs used to describe control behaviors:
AND
—used to describe a parallel condition where two or more sequences of 
data processing functional behavior (branches or processes) are executed 
concurrently.
