Auditors: competence and independence

A program is only as good as the people doing the audits. Build a pool large enough that no auditor does more than one audit a month, from more than one department.

StepWhat it takesEvidence on file
SelectedCurious, respected on the floor, comfortable asking questions; from purchasing, engineering, inspection, planningNomination by the program owner

Lead auditorA lead auditor course and several audits led wellCourse certificate; reports

Independence is about the work, not the job title. An auditor must not audit their own work or their own area. Record on the Auditors tab, for each person, the areas they must not audit, and check the Independent column on every line of the schedule.

A management aid, not certification or a registrar audit. Using it does not by itself show conformity to AS9100D or any other standard, and your customers' requirements may add to it.

Clause numbers refer to AS9100D (SAE AS9100 Rev D) unless another document is named. The standards' text is not reproduced here: use your own licensed copy.

Aegis Insights are our own guidance, labeled wherever they appear: how we approach this work, not a requirement of any standard or customer.
