# Impact settings

The **Impact** tab in [Project Settings](/sleuth-dora/settings/project.md) is where configuration changes are made to the impact sources in your project. Impact sources allow to Sleuth verify your deploys health by tracking the values from your **errors** or **metrics** and associating them with your deploys.
