 Use case diagrams builds interaction diagrams (sequence diagrams)
 Activity diagrams builds interaction diagrams (sequence diagrams)
 System sequence diagrams builds interaction diagrams (sequence diagrams)
o Difference (:System) and (:Controller) and (:Customer) – becomes more detailed
 Requirements state machine diagrams builds design state machine diagram
 Design class diagram builds package diagrams
