Production Readiness Checklist for Custom Execution Engines

Custom execution can unlock performance and flexibility. Without production standards, it can also increase incident risk.

Decision question

Is your custom execution path ready for production traffic now?

Checklist

1. Ownership Named owners for planner, runtime behavior, and release decisions.
2. Observability Metrics, logs, and traces tied to execution stages and failure points.
3. Rollback Fast fallback path to prior execution strategy.
4. Capacity limits Tested thresholds for concurrency, memory, and queue pressure.
5. Data quality controls Guardrails for schema drift and invalid input behavior.
6. Release gating Canary criteria, success thresholds, and automated abort rules.
7. Runbook On-call procedures with known-failure signatures.

Recommendation

Do not ship production-critical workloads until all seven areas are explicit and validated.

KPI target example

• zero priority incidents in first 30 days post-rollout
• rollback execution under 10 minutes in simulation
• diagnosis time under 20 minutes for known failure classes
