A **Group** is an entity within the [[Foundation (CSDM domain)|Foundation domain]] of the [[Common Service Data Model|Common Service Data Model]] (CSDM), a reference architecture developed by [[ServiceNow|ServiceNow]] that provides prescriptive guidance on service-related definitions and data modeling within the ServiceNow AI Platform. A Group represents a set of [[User (CSDM)|users]] who share a common purpose, performing tasks such as approving change requests, resolving incidents, receiving email notifications, or performing work order tasks. Groups are recorded in the sys_user_group table and are part of the [[Common Data (CSDM)|Common Data (CSDM)]] shared throughout the ServiceNow AI Platform. Groups are not [[Configuration item|configuration items]] but serve as critical referential data used across the [[Configuration management database|CMDB]], including identifying management of a CI through the Managed by Group attribute and support for a CI through the Support Group attribute. Any business rules, assignment rules, system roles, or attributes that refer to a group apply to all group members automatically. The [[Teams (CSDM)|Teams]] capability introduced in CSDM 5 provides a related list on CIs that associates groups based on group type (Change Group, Managed by Group, Support Group), enabling flexibility in tracking different types of groups assigned to a CI without adding multiple attributes to CI forms. ServiceNow recommends establishing Group data as part of the Foundation stage of [[CSDM Adoption Stages|CSDM adoption]].
