A defect that passes internal controls and reaches the next process, customer, or end user.
Defect escapes indicate gaps in prevention, detection, or response across the quality system.
Reducing escapes is a core objective for supplier quality teams and customer-facing operations.
Typical escape paths
Common paths include weak sampling plans, unclear acceptance criteria, rushed final checks, and poor escalation discipline.
Data handoff gaps between factory floor and office review can also delay reaction until products are already shipped.
Containment and recurrence prevention
Immediate containment limits further impact, but long-term prevention requires root cause analysis and systemic corrective actions.
Teams should track escape categories to prioritize high-frequency and high-severity failure modes.
Key takeaways
- Defect escapes reveal control gaps that must be addressed at system level.
- Containment and corrective action should be tracked as one closed loop.
- Unified records improve response speed and accountability.
