Symbol overview BPMN 2. 0

Symbol	Name	Description

Symbol	Name	Description
	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.
