 +====== Don't use mixed gateways ======
 +
 +{{tag>gateway mixed_gateway}}
 +
 +Gateways classification:
 +
 +  * diverging (split) - one incoming flow, several outgoing flows
 +  * converging (join) - several incoming flows, one outgoing flow
 +  * mixed - several incoming flows and several outgoing flows
 +
 +Although mixed gateways are allowed it's better to avoid them.

 +The process will hang at the first gateway because it'll wait for two tokens to arrive but only one will.
 +===== Notes =====
 +
 +[[https://www.omg.org/spec/BPMN/2.0.2/PDF|BPMN 2.0.2 spec]] (p. 287) while not prohibiting mixed gatways completely treats them as bad practice:
 +
 +> The Gateway controls the flow of both diverging and converging Sequence Flows. That is, a single Gateway could have multiple input and multiple output flows. Modelers and modeling tools might want to enforce a best practice of a Gateway only performing one of these functions. Thus, it would take two sequential Gateways to first converge and then to diverge the Sequence Flows.
 +
 +As the examples above illustrates, mixed gateways may make the diagram confusing or erroneus so it's better to avoid them. Split the mixed gateway into two - converging followed by diverging.
