Create UML state machine diagrams that describe the life cycle of a business object.

Link use cases to state transition diagrams.

Convert activity diagrams to IDEF format.

Understand alternative legacy approaches the UML standard, including flowcharting, block diagrams and Data Flow Diagrams (DFD)
