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

16. When to use advanced features? Avoid functional decomposition! Fig. 5.16 [Arlow & Neustadt 2005] 16 Advanced Use Case Modeling
