ServiceNow Enterprise Architecture (EA) is a module/package on the ServiceNow platform intended to help organizations model and manage enterprise architecture artifacts—applications, technologies, business capabilities, and related dependencies—using ServiceNow’s data model (notably the Common Service Data Model, CSDM) as a backbone. ServiceNow describes the EA module as integrated with operational data (CMDB/IT operations, SPM/APM data, workflows) so that architecture decisions can be connected to execution and governance rather than maintained in a separate EA repository.
ServiceNow groups "Enterprise Modeling & Visualization," "Application Rationalization," "Business Capability Management," and "Technology/Information Portfolio Management" concepts under this EA offering, with an emphasis on portfolio decisions (invest/sustain/retire) and alignment to strategy.
