Hand over a model service with operational ownership

Handover is complete when people know who owns uptime, model decisions, data, alerts and rollback. A repository and dashboard cannot make decisions during an incident. Record named roles, escalation and the approved fallback.

A machine-checkable packet

The deployment lab creates an illustrative ownership record for a synthetic service.

from deployment_cases import handover_case

result = handover_case()
assert result["complete"] is True
packet = result["packet"]
print(packet["service_owner"], packet["decision_owner"], packet["fallback"])

It separates service owner (ml-platform), decision owner (retention-operations), data owner and on-call route. It records model version, monthly review, alert routes, fallback, rollback runbook, access review and known limits.

Every name is illustrative. No real NeuraPath team, on-call rotation or deployed service is claimed.

Separate responsibilities

The service owner handles availability and platform changes. The decision owner owns threshold and intervention policy. The data owner handles source definitions and quality. Model maintainers own evaluation and candidate changes. Security/privacy owners review access and incidents where appropriate.

Define who can pause, rollback and approve. Give the on-call useful alerts with runbook links, not raw model metrics without action. Maintain contact rotation and test permissions.

Transfer evidence and limitations

Include architecture, schema, data/model lineage, golden requests, evaluation report, dashboards, service objectives, dependencies, cost, change procedure and incident history. State unsupported populations and stale-label delays. Schedule a walkthrough and recovery exercise.

Handover does not end model work. Set review cadence and decommission criteria. The Data Science course treats operating ownership as a capstone deliverable.

Exercise

Create a RACI-style map for one model service, run a mock alert from detection through rollback and update the packet with missing decisions and permissions.
