Emergency Change Process

When to Use Emergency Process

Emergency changes are ONLY allowed for:

  • P1 Incidents: Production system down, trading halted
  • Security Vulnerabilities: Critical CVE requiring immediate patch
  • Data Corruption: Risk of data loss or corruption
  • Regulatory Deadline: Miss filing deadline without immediate fix

Emergency changes are NOT allowed for:

  • Feature requests (even if "urgent")
  • Performance optimizations
  • Technical debt
  • Convenience

Emergency Change Procedure

1. Incident Declaration (T+0 minutes)

  • Incident Commander declares emergency
  • Severity: P1 (Critical)
  • Impact: [Trading halted / Security breach / Data loss]

3. Implementation (T+30 minutes)

  • Follow abbreviated change process
  • Minimum: Peer review of code
  • Deployment: As fast as safely possible
  • Monitoring: All hands on deck

4. Documentation (T+60 minutes - within 1 hour of fix)

  • Create Change Request (CR) retroactively
  • Document what was changed, why, by whom
  • Document approvals (even if verbal)
  • Attach incident report

5. Validation (T+120 minutes - within 2 hours)

  • Verify fix resolved issue
  • No new issues introduced
  • System stability confirmed
  • Stakeholders notified

6. Post-Incident Review (T+48 hours - within 2 days)

  • PIR conducted
  • Root cause analysis
  • Permanent fix planned (if emergency was temporary)
