Gateway
A BPMN gateway is used to create a split in the process model, leading into different branches. Each branch can have its own condition. In this example, the process is split into two branches. The first branch is executed if its condition is met. If it is not met, the second branch is evaluated. If the condition of the second branch is met, it is executed. If neither branch is executed, the process continues with the next task after the converging gateway at the end.
