====== 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.
