An External Failure is any defective item, unit, or output that passes through an entire process and is received by the customer.

External Failures lead directly to customer dissatisfaction. External Failures are very costly, as they must not only be fixed, but customer perceptions must be repaired by addressing the Voice of the Customer. Non-value added activities are usually involved, if not a cause of External Failures.
