the warehouse worker can already start packaging the goods. This clerk's task, which is followed by the exclusive
gateway “mode of delivery”, is a good example for clarifying the recommended usage of a gateway: The gateway is not
responsible for the decision whether this is a special or a postal shipment. Instead, this decision is undertaken in the
activity before. The gateway only works as a router, which is based on the result of the previous task, and provides
alternative paths. A task represents an actual unit of work, while a gateway is only routing the sequence flow.
