AS9100 Audit Load at 52% corrective-action follow-up allowance: a worked example

Push corrective-action follow-up allowance up to 52% and the picture changes. This example computes every intermediate figure at that operating point. a quality manager needs to plan audit support hours before a customer, registrar, or internal AS9100 audit

The inputs for this scenario

  • AS9100 evidence items: 180 records (unchanged)
  • Audit evidence review pace: 2.5 records/min (unchanged)
  • Corrective-action follow-up allowance: 52 % (raised for this scenario; the documented default is 45)

Working through the calculation

  • Applying the documented formula (Base audit evidence review time = AS9100 evidence items รท review pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 109 audit hr for total as9100 audit load, the number this scenario is built around.
  • At this operating point the engine returns 72 audit hr for base audit evidence review time.
  • At this operating point the engine returns 52 % for corrective-action follow-up allowance.
  • At this operating point the engine returns 2.5 records/min for audit evidence review pace.

How this compares with the baseline

  • Against the tool's baseline example, where corrective-action follow-up allowance sits at 45% and the headline result is 104 audit hr, this scenario comes in 4.83% above the baseline at 109 audit hr.
  • It turns a count of evidence records and a review pace into base review hours, then adds a percentage allowance for corrective-action follow-up. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
