If this Element of the investigation confirms the OOS consequence and identifies the foundation lead to, the investigation could be finished.
Many of your techniques Employed in failure Investigation are also used in the Evaluation of no fault found (NFF) which is a phrase Utilized in the sphere of upkeep to explain a problem in which an originally reported mode of failure cannot be duplicated because of the analyzing technician and thus the potential defect cannot be preset.

In conclusion, the ideal exercise, unquestionably, is to reduce the era of failures. Watchful description of test techniques and reportable values, together with suitable process suitability parameters, may also help avoid test end result failures and anomalies. Scientifically audio test system advancement and validation techniques, a well-created instrument/products qualification, and a strong metrology program, combined with qualification and education of analysts in essential laboratory abilities and analytical approaches—and unambiguous, well-created test approaches in addition to a obvious and extensive investigation process—should help limit glitches and failures.
