# Exclusive gateway
Used to create diverging, alternative paths within a process when only one of the alternative paths can be taken.
Conditions are evaluated on the outgoing sequence flows, not on the gateway itself. Each condition expression must evaluate to `true` or `false`. Collibra evaluates the outgoing sequence flows in the order defined by the Flow order property and follows the first one whose condition evaluates to `true`.
{% hint style="info" %}
If more than one condition evaluates to `true`, only the first defined sequence flow is followed. Design your process to ensure conditions are mutually exclusive. If no condition evaluates to `true`, the process gets stuck. To prevent this, mark one outgoing sequence flow as a default flow.
{% endhint %}

| [Asynchronous](/workflows/designing-workflows/processes/process-execution.md#asynchronous-activities) | Whether the activity starts as an asynchronous job, placing a transaction boundary before the activity:
- No (default): Synchronous.
- Yes, exclusive: Asynchronous and with no other exclusive asynchronous jobs in the same process run at the same time.
- Yes, non-exclusive: Asynchronous and can run concurrently with other asynchronous jobs in the same process.
|
| Leave asynchronously | Whether the activity leaves as an asynchronous job after it completes, placing a transaction boundary before the process advances to the next element:
- No (default): Synchronous.
- Yes, exclusive: Asynchronous and with no other exclusive asynchronous jobs in the same process run at the same time.
- Yes, non-exclusive: Asynchronous and can run concurrently with other asynchronous jobs in the same process.
