Creating a scenario diagram in IDEF3 process modeling
The scenario diagram in IDEF3 process modeling is the top-level diagram process flow diagram for a part of a business or a system. You can build a scenario diagram by creating a new IDEF3 process flow diagram. However, you cannot designate an existing IDEF3 diagram as a scenario diagram.
1 Click New > Diagram > IDEF3 Process Flow.
2 In the IDEF3 Diagram properties dialog box, select the Scenario Diagram check box.
3 Type a scenario name, and then click OK.
