Cutover Readiness

Go/No-Go gates for finance — objective evidence over optimism.

Cutover Readiness Checklist (Go/No-Go)

In financial services, the cutover is a controlled risk event. This checklist defines objective gates, required evidence, and the accountable owner for each readiness area.

Gate Readiness criteria Evidence required Owner Go/No-Go rule
G1 — Data integrity Reconciliation within tolerance across all account types and ledgers Signed reconciliation report + independent QA validation Data Migration Lead No-Go if tolerance breached or exceptions untriaged
G2 — Channel stability Login, account view, and critical journeys stable under peak load Performance test results + monitoring dashboards + error budget thresholds Channels Lead No-Go if critical journey fails or sustained error rate above threshold
G3 — Payments continuity Payments scenarios validated end-to-end (incl. retries and exceptions) Test evidence; reconciliation; contingency plan for failed processing Payments Lead No-Go if any critical payment scenario remains unproven
G4 — Monitoring & incident response War-room staffed, runbooks validated, escalation paths clear Incident drill outcome report + on-call rota + severity triage matrix Ops Lead No-Go if staffing gaps or runbooks unvalidated
G5 — Rollback safety Rollback plan tested, timeboxed, and decision authority explicit Rollback rehearsal report + decision log + “point of no return” definition Programme Director No-Go if rollback untested or authority unclear
G6 — Customer communications Customer messaging, scripts, and fallback channels ready Comms pack + branch scripts + contact centre FAQ + update cadence plan Comms Lead No-Go if customer comms is incomplete or unapproved
“Ready” is not a milestone. It’s a body of evidence.
