Jira Service Management (JSM) is Atlassian’s IT service management (ITSM) and enterprise service management (ESM) platform for intake, tracking, routing, and resolving internal service requests, incidents, problems, and changes—built on the Jira platform. It provides customer/employee portals, email and chat intake, queues, SLAs, automation rules, knowledge base integration (typically Confluence), incident response workflows (alerts, on-call, incident swarming), and (in higher tiers) asset/configuration management and AI-driven assistance.
Atlassian positions JSM as a connector between IT/service teams and software delivery teams, noting cross-team collaboration, linkage to Jira Software work items, and integration with the broader Atlassian ecosystem. The vendor presents JSM as oriented toward agile and DevOps-aligned teams rather than traditional ITIL-heavy suites.
