Production Outage Operational Postmortem Readiness Checklist

Role: Principal Site Reliability Engineer and Infrastructure Operations Director

Context

• Incident reference: {{incident_identifier}}
• Core impacted architecture: {{affected_subsystems}}
• Service Level Agreement threshold breached: {{sla_breach_threshold}}
• Primary failure vector: {{root_cause_summary}}
• Target deployment infrastructure: {{deployment_environment}}
• Assigned engineering unit: {{remediation_owner_team}}

Task

Generate an exhaustive operational postmortem validation checklist that audits diagnostic telemetry, architectural regression tests, failover runbooks, and preventive controls to guarantee zero recurrence across the operational environment.

Method

1. Inspect {{root_cause_summary}} against the baseline architecture of {{affected_subsystems}} to define mandatory containment boundary checks.
2. Detail pre-incident telemetry gaps within {{deployment_environment}} that delayed root-cause detection past {{sla_breach_threshold}}.
3. Establish infrastructure-level sanity verification items for all stateful and stateless dependencies.
4. Design automated health probe and synthetic canary test checklists for {{affected_subsystems}}.
5. Formulate actionable verification checkpoints for {{remediation_owner_team}} to enforce in continuous integration pipelines.
6. Detail configuration drift and environment parity checks between staging and {{deployment_environment}}.
7. Map explicit operational handoff validation criteria before incident {{incident_identifier}} is officially marked resolved.

Constraints

• MUST express every checklist item as an actionable, imperative verification command with pass/fail criteria.
• MUST organize checklist items chronologically from immediate telemetry remediation to long-term architectural hardening.
• MUST NOT include vague advice or generic software engineering maxims.
• Operational checklist must not exceed 25 total line items.

Output format

1. Incident Overview & Blast Radius Context

(Concise tabular summary of the failure mode, affected nodes, and SLA impact)

2. Immediate Infrastructure & Telemetry Remediation Checklist

(Numbered list of 6-8 operational verification checks with markdown checkboxes [ ])

3. Architectural Resilience & Automated Guardrail Checklist

(Numbered list of 6-8 deep technical checks with markdown checkboxes [ ])

4. Operational Sign-Off & Runbook Validation

(Numbered list of 4-6 verification steps required before closing postmortem)

Self-review

• Confirm all 6 variables ({{incident_identifier}}, {{affected_subsystems}}, {{sla_breach_threshold}}, {{root_cause_summary}}, {{deployment_environment}}, {{remediation_owner_team}}) are addressed.
• Ensure each checklist item specifies the exact mechanism for validation.
• Verify no placeholders or unresolved markers exist in the generated checklist.
