By using drivers, you can group your engagement questions into certain topics. This will make it easier to evaluate results based on a specific topic.

When you go to Studio > Engagement > Drivers, you can add a new driver by clicking on the "Add New Engagement Driver" in the right upper corner

Give your new driver a clear and understandable name. You can add a description to give more information about this driver.

The results of the questions linked to a sub-driver will be taken into account of the parent driver as well. Mor info about this calculation, you can find in this article:
