Pharmaceutical Packaging & Serialization worked example

Vision Reject Rate at 99% target vision reject rate: a worked example

This scenario runs the vision reject rate calculation on the strong side: 99% target vision reject rate, with every other input held at its documented default. Use it when vision reject rate in pharmaceutical packaging and serialization needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Units rejected by vision inspection: 8 count (unchanged)
  • Total units inspected: 250 count (unchanged)
  • Target vision reject rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Vision reject rate = vision reject rate count ÷ total vision reject rate population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for vision reject rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for vision reject rate gap to target.
  • At this operating point the engine returns 8 count for vision reject rate count.
  • At this operating point the engine returns 250 count for total vision reject rate population.

How this compares with the baseline

  • Against the tool's baseline example, where target vision reject rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it during a run or shift review to gauge inspection reject performance and whether the line is meeting its reject target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Vision reject rate: 3.2 % (headline result)
  • Vision reject rate gap to target: 95.8 points
  • Vision reject rate count: 8 count
  • Total vision reject rate population: 250 count

Run it with your numbers

  • Every input above is editable in the live Vision Reject Rate calculator, which recalculates instantly and can be shared with the inputs intact.
