**Service Mapping** is a [[ServiceNow|ServiceNow]] product within the [[IT operations management (ServiceNow)|IT Operations Management]] (ITOM) suite that provides capabilities for automatically discovering and mapping the components that make up [[Application Service (CSDM)|Application Services]] within the ServiceNow AI Platform. Service Mapping leverages tables from the [[Service Delivery (CSDM domain)|Service Delivery domain]] of the [[Common Service Data Model|Common Service Data Model]] (CSDM) to create and maintain service dependency maps through top-down discovery starting from entry points.
Service Mapping creates Mapped Application Services (cmdb_ci_service_discovered) by discovering the [[Application (CSDM)|Applications]], infrastructure [[Configuration item|configuration items]], and [[CMDB relationship|CMDB relationships]] that support a service, starting from defined entry points such as URLs or load balancers. The discovered service maps show dependencies between components, enabling [[Impact analysis (ServiceNow)|impact analysis]] for [[Incident management (ITSM)|Incident]], [[Problem management|Problem]], and [[Change management (ITSM)|Change]] processes. [[Event Management (ServiceNow)|Event Management]] uses Service Mapping data to monitor Application Service performance and identify health issues for related infrastructure CIs. Service Mapping integrates with [[Business Application (CSDM)|Business Applications]] from the [[Design & Planning (CSDM domain)|Design & Planning domain]] through the "Uses::Used by" relationship, enabling [[Enterprise Architecture (ServiceNow)|Enterprise Architecture]] capabilities such as Technology Portfolio Management risk assessment. When Service Mapping is not yet implemented, organizations can use [[Dynamic CI Group (CSDM)|Dynamic CI Groups]] as query-based Application Services or manually create services using the Application Service wizard across the [[CSDM Service Life Cycle|CSDM Service Life Cycle]].
