Special Process Audit Load at 40% finding and follow-up allowance: a worked example

Suppose finding and follow-up allowance falls to 40%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate audit hours for aerospace special processes from process evidence items, review pace, and corrective-action allowance.

The inputs for this scenario

  • Special-process evidence records to review: 125 records (held at the documented default)
  • Special-process audit review pace: 1.6 records/min (held at the documented default)
  • Finding and follow-up allowance: 40 % (the input this scenario stresses; the baseline uses 55)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base special-process review time = evidence records รท audit review pace.
  • Special process audit load works out to 109 audit hr at these inputs, and this is the headline figure for the scenario.
  • Base special-process review time works out to 78.13 audit hr at these inputs.
  • Finding and follow-up allowance works out to 40 % at these inputs.
  • Special-process audit review pace works out to 1.6 records/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where finding and follow-up allowance sits at 55% and the headline result is 121 audit hr, this scenario comes in 9.68% below the baseline at 109 audit hr.
  • It computes total audit hours by dividing evidence records by a review pace and adding an allowance for documenting and following up on findings. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Special process audit load: 109 audit hr (headline result)
  • Base special-process review time: 78.13 audit hr
  • Finding and follow-up allowance: 40 %
  • Special-process audit review pace: 1.6 records/min
