Customer-onboarding, order-to-fulfillment, renewal — processes that touch five systems executed as one coherent flow with rollback and audit.
The hardest operational problems aren't inside a system; they're between systems. Cross-system orchestration turns those choreographies into first-class objects — visible, testable, and owned.
Every system touched, every state transition, every compensation is explicit.
Long-running flows survive restarts and partial failures. No work is lost, no work is duplicated.
Bottlenecks, retries, and breakage patterns surface as metrics. Flows improve with real data.
Multi-step flows with compensation — system A's action rolls back if system C fails.
In-flight instances finish on the version they started; new starts use the latest.
Any step can request human approval with full context; humans don't start from zero.
Per-flow health, volume, and SLA attainment visible — with alerts before breach, not after.
