# Parallel gateway

Used to combine and create parallel flows to model situations where more than one path is executed in parallel.

A parallel gateway can act as a fork, a join, or both:

* **Fork**: All outgoing sequence flows are followed simultaneously, creating one parallel execution for each.
* **Join**: Execution waits until all incoming sequence flows have completed before the process continues.

If the same gateway has multiple incoming and multiple outgoing sequence flows, it first joins all incoming executions, then forks into parallel paths.

{% hint style="info" %}
Conditions on sequence flows connected to a parallel gateway are ignored. All outgoing flows are always followed.
