Glass Install Yield at 70% target glass install yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target glass install yield to 70%, then walk the calculation through step by step. Calculate first-pass yield for windshield, side window, destination glass, or coach glazing installation.

The inputs for this scenario

  • Glass openings passing first inspection: 188 units (held at the documented default)
  • Glass openings installed: 200 units (held at the documented default)
  • Target glass install yield: 70 % (the input this scenario stresses; the baseline uses 97)

Working through the calculation

  • The calculation starts from the formula this tool documents: Glass Install Yield = glass openings passing first inspection ÷ glass openings installed.
  • Rate works out to 94 % at these inputs, and this is the headline figure for the scenario.
  • glass install yield gap to target works out to -24 points at these inputs.
  • Affected count works out to 188 count at these inputs.
  • Total count works out to 200 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target glass install yield sits at 97% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target glass install yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts openings, not defect severity — one opening that needs a full cut-out and re-bond counts the same as one with a minor trim reset, so yield alone can understate true rework cost.

Results at a glance

  • Rate: 94 % (headline result)
  • glass install yield gap to target: -24 points
  • Affected count: 188 count
  • Total count: 200 count
