Test Lot Sample Size at 23% sample review and hold allowance: a worked example

This scenario runs the test lot sample size calculation on the strong side: 23% sample review and hold allowance, with every other input held at its documented default. a quality manager needs to plan sampling labor for approved lots

The inputs for this scenario

  • Required lot sample records: 96 sample records (unchanged)
  • Sample records completed per hour: 16 sample records / hr (unchanged)
  • Sample review and hold allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base sample administration hours = required lot sample records รท sample records completed per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 7.38 hr for required lot sampling workload hours, the number this scenario is built around.
  • At this operating point the engine returns 6 hr for base sample administration hours.
  • At this operating point the engine returns 23 % for sample review and hold allowance.
  • At this operating point the engine returns 16 sample records / hr for sample records completed per hour.

How this compares with the baseline

  • Against the tool's baseline example, where sample review and hold allowance sits at 20% and the headline result is 7.2 hr, this scenario comes in 2.5% above the baseline at 7.38 hr.
  • Use it when scheduling acceptance testing for a new or repeat energetic-material lot and you need to reserve QA bench hours before release. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
