Final Test Time at 21% test allowance for retest and documentation: a worked example

Push test allowance for retest and documentation up to 21% and the picture changes. This example computes every intermediate figure at that operating point. Use it when scheduling final inspection, drive test, lift test, brake test, hydraulic leak test, charger check, safety interlock verification, or customer acceptance.

The inputs for this scenario

  • Final-test workload: 24 tests (unchanged)
  • Final-test completion rate: 3 tests / hr (unchanged)
  • Test allowance for retest and documentation: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base final test time = final-test workload รท final-test completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.68 hr for adjusted final test time, the number this scenario is built around.
  • At this operating point the engine returns 8 hr for base final test time.
  • At this operating point the engine returns 21 % for test allowance for retest and documentation.
  • At this operating point the engine returns 3 pieces / min for final-test completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where test allowance for retest and documentation sits at 18% and the headline result is 9.44 hr, this scenario comes in 2.54% above the baseline at 9.68 hr.
  • It converts a final-test workload into hours at a given completion rate, then inflates that base time by a retest-and-documentation allowance. 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.

Results at a glance

  • Adjusted final test time: 9.68 hr (headline result)
  • Base final test time: 8 hr
  • Test allowance for retest and documentation: 21 %
  • Final-test completion rate: 3 pieces / min
