What is the difference between a Cat I PQDR and a Cat II PQDR?
Cat I PQDRs report a critical defect which may cause death, injury, or sever occupational illness; would cause loss or major damage to a weapon system; critically restricts the combat readiness capabilities of the using organization; or any defect which would result in production line stoppage. Cat II PQDRs report a product quality deficiency which does not meet the criteria set forth in Category I. Cat II is normally used for reporting major and minor defects.
