# Alert Grouping

Consolidate related alerts into a single incident to cut noise, reduce alert fatigue, and speed up response across one or more services.

Alert Grouping is designed for incident responders and operations teams who want to streamline their workflow by reducing noise from multiple alerts and focusing on meaningful incidents. By consolidating related alerts into a single incident, this feature minimizes alert fatigue and accelerates response times, allowing teams to manage incidents more effectively across multiple services.

> **AIOps / Signal Intelligence Feature:** This feature is included with the [PagerDuty AIOps](/ai-automation/aiops/overview) add-on, or included as Signal Intelligence in PD Reliability Platform plans. To sign up for a trial of PagerDuty AIOps features, read [PagerDuty AIOps Trials](/ai-automation/aiops/overview#pagerduty-aiops-trials).

> **Required User Permission:** Users with the following roles can edit a service’s Alert Grouping settings:
>
> - Account Owner
> - Admin and Global Admin
> - User
> - Manager base role and team roles
>   - Manager team roles can only manage services associated with their team.

> **Global Alert Grouping:** By default, Alert Grouping groups alerts on a single technical service. If you’d like to expand scope across more than one service, please read [Global Alert Grouping](/ai-automation/aiops/noise-reduction/alert-grouping/global-alert-grouping), which allows you to configure a multiservice group, and group alerts from different services into a single incident.
