# fail>: Makes the workflow failed

**fail>** always fails and makes the workflow failed.

This operator is useful used with [if> operator](/products/customer-data-platform/data-workbench/workflows/operators/if) to validate results of a previous task with `_check` directive so that a workflow fails when the validation doesn't pass.


```
+fail_if_too_few:
  if>: ${count < 10}
  _do:
    fail>: count is less than 10!
```

## Options

* **fail>**: STRING
Message so that `_error` task can refer the message using `${error.message}` syntax.
