Composite Yield at 99% target composite first-pass yield: a worked example

What does the result look like when target composite first-pass yield reaches 99%? The full calculation is worked below with real intermediate numbers. tracking first-pass yield for composite manufacturing

The inputs for this scenario

  • Composite parts passing first time: 112 parts (unchanged)
  • Composite parts inspected or produced: 125 parts (unchanged)
  • Target composite first-pass yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Composite Yield = composite parts passing first time ÷ composite parts inspected or produced × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 89.6 % for composite yield, the number this scenario is built around.
  • At this operating point the engine returns 9.4 points for composite yield gap to target.
  • At this operating point the engine returns 112 count for composite parts passing first time.
  • At this operating point the engine returns 125 count for composite parts inspected or produced.

How this compares with the baseline

  • Against the tool's baseline example, where target composite first-pass yield sits at 95% and the headline result is 89.6 %, this scenario lands almost exactly on the baseline at 89.6 %.
  • A figure at this level is achievable when target composite first-pass yield is genuinely sustained, not just peaked for a shift. It measures only first-pass pass rate; it does not weight defect severity, separate scrap from reworkable rejects, or capture downstream escapes found after the inspection point.

Results at a glance

  • composite yield: 89.6 % (headline result)
  • composite yield gap to target: 9.4 points
  • composite parts passing first time: 112 count
  • composite parts inspected or produced: 125 count
