Start

An event object that specifies the beginning of a business process. Each process must have only one Start workstep.

Activity

This activity represents the basic unit of work that you can assign to one of the following performer types: User (a valid human performer or group), Adapter, or Subprocess.

Decision

This gateway represents a decision point in the process flow. If the specified condition is not met, the default branch is taken.

Exclusive Or-Join

This gateway enables the process flow to proceed only once from multiple previous worksteps to a next workstep, and terminates any other human-performed previous worksteps. This shape is not available for Web Applications.

Or-Join

This gateway connects multiple predecessor worksteps and one successor workstep. The successor workstep is performed if any of the predecessor worksteps have been completed.

And-Gateway

This gateway can act as an And Join or as a Split (or And-Fork). When it connects multiple predecessor worksteps to a single successor workstep, it acts as an And-Join. When it connects one predecessor workstep to multiple successor worksteps, it acts as a Split (or And-Fork). The successor worksteps are performed in parallel and only if the predecessor was completed. This enables you to synchronize the completion of multiple predecessor worksteps. This shape (gateway) is not available for Web applications.

Message

An intermediate workstep in a process, indicating that the workstep is waiting for a message or will send a message when it is activated. Messages can also be assigned to the Start or End of a process.

End

An event object that signifies that the application has come to a normal end. You can add multiple End worksteps in a process.
