# Create a pool and lanes

To help visualize the workflow and identify the process participants, especially in more complex diagrams, you can make use of [pools](/workflows/designing-workflows/processes/shape-repository/pool.md) and [lanes](/workflows/designing-workflows/processes/shape-repository/lane.md). Collibra Platform workflows usually have one pool that represents the process while lanes represent different participants or roles in the process.

{% hint style="info" %}
Pools and lanes are optional in Workflow Designer.
{% endhint %}

{% hint style="success" %}
Although lanes are merely visual aids and play no role in the execution of the workflow, use one lane per each stakeholder.
{% endhint %}

{% stepper %}
{% step %}
From the **Swimlanes** section of the [**Shape repository**](/workflows/designing-workflows/processes/shape-repository.md), drag a **Pool** to the canvas.

{% hint style="info" %}
Each pool contains by default one lane.
{% endhint %}
{% endstep %}

{% step %}
To add a second lane, from the **Swimlanes** section of the **Shape repository**, drag a **Lane** to the pool.\ <i class="fa-chevrons-right">:chevrons-right:</i> You now have a pool with two lanes:

{% endstep %}

{% step %}
Move any existing diagram elements inside the lanes.
{% endstep %}

{% step %}
Rename the pool to match the name of the process.
{% endstep %}

{% step %}
Rename the lanes to match the participants in the process.
{% endstep %}
{% endstepper %}

## What's next

When you have added your pool and lanes, you can add your start and end events.
