They involve safety issues, data integrity issues, isolated tests that may not affect other tests, and cosmetic blemishes in the test article. DRs have levels of significance that affect the test schedule. Degree of significance requiring a level of urgency for corrective action.

Specific document item requirement and expected results. Conditions and prior sequence of steps preceding a test event. The Test Direc- tor should define WHAT constitutes a test event in the SIVP and event criteria for recording a DR. When test events such as failures occur, a Discrepancy Report (DR) is recorded. We refer to the occurrence of a discrepancy as a test event. Discrepancy Reports (DRs) Inevitably, discrepancies will appear between actual test data and bounded expected results spec- ified in the SPS or item development specification. Form, fit, and function checks of the UUT that were suc- cessfully completed and not affected by any corrective actions are not re-verified. During regression testing only those aspects of the component design that have been impacted by a corrective action are re-verified. Corrective action, WHAT tests impacted by the failure must be repeated before you can resume testing at the test sequence where the failure occurred? The answer resides in regression testing.
