•OV-02 Operational Resource Alternative Diagram: You can model Activities, the Performer that performs them (through the ActivityPerformedbyPerformer relationship), what Resources the Activity changes (through the ActivityChangesResource line), and what Capabilities the Activity can perform (through the ActivityAbletoPerformCapability line). See OV-02 Operational Resource Flow alternative diagrams.
