Seam Defect Rate at 99% target seam defect rate: a worked example

Push target seam defect rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when seam defect rate in textiles and apparel manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Seams rejected at inspection: 8 count (unchanged)
  • Total seams inspected: 250 count (unchanged)
  • Target seam defect rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target seam defect rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes rejected seams divided by seams inspected, times 100, and reports the point gap to 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

  • Seam defect rate: 3.2 % (headline result)
  • Seam defect rate gap to target: 95.8 points
  • Seam defect rate count: 8 count
  • Total seam defect rate population: 250 count
