A Sequence Flow is used to show the order of flow elements in a process or choreography (Figure 12).
Figure 12 -- Sequence Flow Drawn between Two Tasks
The source and target of a Sequence Flow must be from the set of the following elements:
• Events (Start, Intermediate, and End events)
• Activities (Task and Sub-Process; for Processes)
• Choreography Activities (Choreography Task and Sub-Choreography)
• Gateways
A Sequence Flow can optionally define a condition expression, indicating that a token will be passed down the
Sequence Flow only if the expression is evaluated to be true.
A Condition expression is typically used when the source of a Sequence Flow is a Gateway or an Activity. A
conditional outgoing Sequence Flow from an Activity is drawn with a mini-diamond (indicator) at the beginning
of the Sequence Flow (Figure 13).
