Drive Test Time at 12% setup and retest allowance: a worked example

Push setup and retest allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning functional test, load test, firmware verification, hipot, thermal run, or end-of-line drive test capacity.

The inputs for this scenario

  • Drives to test: 120 drives (unchanged)
  • Drive test completion rate: 12 drives / min (unchanged)
  • Setup and retest allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base drive test time = drives to test รท drive test completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 min for required drive test time, the number this scenario is built around.
  • At this operating point the engine returns 10 min for base drive test time.
  • At this operating point the engine returns 12 % for drive test allowance applied.
  • At this operating point the engine returns 12 pieces / min for drive test completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup and retest allowance sits at 10% and the headline result is 11 min, this scenario comes in 1.82% above the baseline at 11.2 min.
  • It computes required drive test time as base time (drives divided by test completion rate) scaled up by a setup-and-retest allowance factor. 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

  • Required drive test time: 11.2 min (headline result)
  • Base drive test time: 10 min
  • Drive test allowance applied: 12 %
  • Drive test completion rate: 12 pieces / min
