Concepts for the description of requirements
(behavior aspects)

• Each Use Case is a scenario
• Actions done by actors in some given order
• Action Activity / Responsibility
• Actor Swimlane / Component
• Order sequence, alternatives, concurrency,
  arbitrary control flows (similar to Petri nets)
• Abstraction refinement of activity / Plug-in
• Data-Flow Object flow / not in UCMs. Question
  what type of data is exchanged (an extension of
  control flow)
• Input assertions for input data flow
• Output assertions for output data flow
• Conditions for alternatives (also in UCMs)
