### Signal to interviewer

I can eliminate recurring failures by combining root-cause discipline with preventive engineering controls.

### Clarify

I would clarify which failures recur most, their user impact, and current ownership and escalation gaps.

### Approach

Use recurring failure eradication: classify repeat issues, prioritize by harm, implement durable fixes, and add prevention checks.

### Metrics & instrumentation

Primary metric: recurrence rate for high-severity failure classes. Secondary metrics: time-to-permanent-fix, post-fix escape rate, and owner accountability completion. Guardrails: temporary patch backlog, unresolved critical clusters, and trust decline in affected cohorts.

### Tradeoffs

Rapid patching restores service quickly but can entrench technical debt. Deeper redesign lowers recurrence but requires more coordination and time.

### Risks & mitigations

Risk: shallow root-cause analysis; mitigate with structured post-incident review templates. Risk: ownership ambiguity; mitigate with clear RACI mapping. Risk: prevention checks become stale; mitigate with periodic verification.

### Example

A document assistant repeatedly mishandles citations, so team adds citation consistency tests and pre-deploy quality gates tied to that class.

### 90-second version

Stop recurring AI failures by turning incidents into preventable classes with clear owners, durable fixes, and enforcement via tests and monitoring.
