Common Modeling Techniques:

Modeling the Behavior of an Element 

To model the behavior of an element: 

• Identify the actors that interact with the element. These include groups that requires a certain behavior to execute their tasks or that are needed directly or indirectly to perform the element's functions 
• Classify actors by recognizing general and more specific roles 
• For each and every actor, examine the primary ways the actor interacts with the element 
• Also take in aspect, the exceptional ways in which the actor interacts with the system 
• Classify these behaviors as use cases by applying include and extend
