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

16. When to use advanced features?
Avoid functional
decomposition!
