15 When to use advanced features?  Use advanced features when they simplify the model  Heavy use of > should be avoided  Many stakeholders, including object modelers misunderstand >  Avoid use case generalization unless abstract parent use cases are used February 2, 2012 Advanced Use Case Modeling

16 When to use advanced features? Avoid functional decomposition! Fig [Arlow & Neustadt 2005] February 2, 2012 Advanced Use Case Modeling
