Connecting referents to transition lines in IDEF3 OSTN diagram
Referents represent objects or information that are critical in the completion of a scenario.
In an IDEF3 OSTN, referents allow you to do the following tasks:
▪span multiple pages or loop back in a diagram layout
▪tie in specific examples of referenced data or objects (for example, screen layouts)
▪associate special constraint sets to object states; that is, associate an elaboration with an object state to describe additional facts, constraints, or decision logic which limit how that object state works
▪form references or links between IDEF3 OSTN diagrams and IDEF3 Process Flow diagrams.
Referents in an IDEF3 OSTN can signify either a UOB, a scenario, or a transition schematic.
1 Draw the referent.
2 Hold down Shift, and then click the transition line (drawn between two states), and the referent symbol you want to connect.
