zero-tolerance-for-failure

Guides failure-prevention culture and operational excellence for mission-critical engineering— zero-defect aspiration vs. error budgets; HRO principles; defense-in-depth; fail-safe / fail-closed; verification gates and independent checks; redundancy and graceful degradation; pre-mortems and FMEA; stop-the-line; defect-escape, near-miss, and repeat-incident metrics; leadership against normalization of deviance—not a blame culture. Use for failure-prevention programs, HRO practices, verification gates, fail-safe design, pre-mortem / FMEA, stop-the-line policies, near-miss reporting, and defect-escape metrics — not limited to SRE error budgets only (site-reliability-engineer), incident command only (incident-management-engineer), backup/restore only (cyber-resilience-engineer), CI lint only (build-validator), agile coaching, HR/legal discipline, or classified ATO work without an operational-excellence lens (classified-cyber-security-senior-manager).
