Pharmaceutical Packaging & Serialization worked example

Vision Reject Rate at 68% target vision reject rate: a worked example

This worked example runs the vision reject rate numbers for a tougher week than the baseline: 68% target vision reject rate instead of the typical 95%. Estimate vision reject rate for pharmaceutical packaging and serialization using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Units rejected by vision inspection: 8 count (held at the documented default)
  • Total units inspected: 250 count (held at the documented default)
  • Target vision reject rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Vision reject rate = vision reject rate count ÷ total vision reject rate population × 100.
  • Vision reject rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Vision reject rate gap to target works out to 64.8 points at these inputs.
  • Vision reject rate count works out to 8 count at these inputs.
  • Total vision reject rate population works out to 250 count at these inputs.

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. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Vision reject rate: 3.2 % (headline result)
  • Vision reject rate gap to target: 64.8 points
  • Vision reject rate count: 8 count
  • Total vision reject rate population: 250 count

Run it with your numbers

  • To rerun this with your own numbers, open the live Vision Reject Rate calculator, set target vision reject rate to your actual value, and adjust the remaining inputs to match your operation.
