Modeling Workflows

Pool

A pool forms a higher-level organizational unit, e.g. a company.

Swimlane

Swimlanes subdivide the pool into subordinate units.

Activity

A work step/activity in a process.

Email / Send

Used to automatically send emails from within the process.

Hidden Subprocess

Symbol for a hidden subprocess.

Signal

Lets the process wait at this point until a specific event/signal occurs.

Start

Serves as a marker for starting a process.

End

Ends the current branch of the process.

Termination Event

When reached, the complete process is terminated.

XOR-Gateway

An exclusive gateway where an output becomes active.

AND-Gateway

A parallel gateway in which all outputs become active.

Boundary Exception

In case of an error, this path becomes active.

Boundary Escalation

In case of an escalation, this path becomes active. The current activity is either ended (interruption – not dashed) or persists (uninterrupted – dashed)

Script Task

Script tasks are automatically processed by the system without the need for user interaction. Script tasks can currently only be used in conjunction with an Actionhandler. The Actionhandler is executed when the sequence flow reaches the script task.

User Task

User tasks describe classic "workflow" tasks in which a user processes a task using the system. The difference to a manual task results from the software-supported processing with the system.

Email Start

Serves as a marker for starting a process by an inbound email (both symbols work, only one is needed).

Complete by Email

Allows for task completion by an inbound email (both symbols work, only one is needed).
