# Decision
A *Decision* task invokes one of the two paths in the workflow, depending on whether the logical expression inside the *Decision* object returns a Yes (True) or a No (False) flag.
To use a *Decision* task, drag-and-drop the *Decision* object onto the workflow designer. Configure the object by right-clicking on the object’s header and selecting *Properties* from the context menu.
This will open the *Decision Properties* window. The configuration window provides the interface to create some decision logic.
In the *Expression* input box, enter an expression. This expression should return a Boolean result, such as True or False. An example of this expression is shown below. The expression here is based on the presence of erroneous records in a *Run* *Dataflow* task object.
{% hint style="info" %}
**Note:** The right-hand pane, *Objects,* displays the object tree. You can double-click on an object to add it to your expression.
{% endhint %}
This concludes the configuration of the *Decision* object in Astera.
