Exclusive gateway (OR)

Level: beginner

The Exclusive gateway (OR) is used when only one of the parallel flows in the process can be selected, for example, you can offer a discount or standard price to a customer (Fig. 1).

In this case, only one of the two actions can be executed.

When diverging, an exclusive gateway usually requires an outgoing default flow. Default flow is activated when it is impossible to activate at least one of the conditional flows.

The converging exclusive gateway is used to merge several parallel flows. In this case, every incoming sequence flow is routed to a single outgoing flow.

For example, after delivery conditions were offered to the customer (either with or without a discount), the quotation must be prepared (Fig. 2).

When the converging Exclusive gateway (OR) is used, the process will continue after either of the incoming flows is activated.
