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 blame culture. Use for failure-prevention programs, HRO practices,
verification gates, fail-safe design, pre-mortem/FMEA, stop-the-line, near-miss reporting, or
defect-escape metrics—not SRE error budgets only (site-reliability-engineer), incident command only
(inci…
