Composite Yield at 68% target composite first-pass yield: a worked example

This worked example runs the composite yield numbers for a tougher week than the baseline: 68% target composite first-pass yield instead of the typical 95%. Calculate first-pass yield for composite parts, panels, coupons, or assemblies.

The inputs for this scenario

  • Composite parts passing first time: 112 parts (held at the documented default)
  • Composite parts inspected or produced: 125 parts (held at the documented default)
  • Target composite first-pass yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Composite Yield = composite parts passing first time ÷ composite parts inspected or produced × 100.
  • composite yield works out to 89.6 % at these inputs, and this is the headline figure for the scenario.
  • composite yield gap to target works out to -21.6 points at these inputs.
  • composite parts passing first time works out to 112 count at these inputs.
  • composite parts inspected or produced works out to 125 count at these inputs.

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 %.
  • Use it at end of shift, daily, or per lot to monitor first-pass quality and to quantify how far the cell sits from its yield goal. 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

  • composite yield: 89.6 % (headline result)
  • composite yield gap to target: -21.6 points
  • composite parts passing first time: 112 count
  • composite parts inspected or produced: 125 count
