Inspection Defect Rate at 1.15% target defect rate: a worked example

Push target defect rate up to 1.15% and the picture changes. This example computes every intermediate figure at that operating point. Use it when quality teams need to track defects such as flash, nicks, short shots, voids, cracks, contamination, dimension misses, durometer misses, or surface blemishes against a target rate.

The inputs for this scenario

  • Rejected elastomer parts: 18 parts (unchanged)
  • Inspected elastomer parts: 1,200 parts (unchanged)
  • Target defect rate: 1.15 % (raised for this scenario; the documented default is 1)

Working through the calculation

  • Applying the documented formula (Inspection defect rate = rejected elastomer parts ÷ inspected elastomer parts × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.5 % for inspection defect rate, the number this scenario is built around.
  • At this operating point the engine returns -0.35 points for defect-rate gap to target.
  • At this operating point the engine returns 18 count for rejected elastomer parts.
  • At this operating point the engine returns 1,200 count for inspected elastomer parts.

How this compares with the baseline

  • Against the tool's baseline example, where target defect rate sits at 1% and the headline result is 1.5 %, this scenario lands almost exactly on the baseline at 1.5 %.
  • It computes the share of inspected elastomer parts that were rejected and the point-gap between that rate and your target defect rate. 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

  • Inspection defect rate: 1.5 % (headline result)
  • Defect-rate gap to target: -0.35 points
  • Rejected elastomer parts: 18 count
  • Inspected elastomer parts: 1,200 count
