Quality Gate Defect Rate at 5.75% target quality gate defect rate: a worked example

Push target quality gate defect rate up to 5.75% and the picture changes. This example computes every intermediate figure at that operating point. measuring defects at a vehicle quality gate

The inputs for this scenario

  • Defects found at the quality gate: 14 units (unchanged)
  • Vehicles inspected at the gate: 120 units (unchanged)
  • Target quality gate defect rate: 5.75 % (raised for this scenario; the documented default is 5)

Working through the calculation

  • Applying the documented formula (Quality Gate Defect Rate = defects found at the quality gate รท vehicles inspected at the gate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.67 % for rate, the number this scenario is built around.
  • At this operating point the engine returns -5.92 points for quality gate defect rate gap to target.
  • At this operating point the engine returns 14 count for affected count.
  • At this operating point the engine returns 120 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target quality gate defect rate sits at 5% and the headline result is 11.67 %, this scenario lands almost exactly on the baseline at 11.67 %.
  • It computes the percentage of inspected vehicles flagged with a defect at a specific quality gate, plus the gap in points to your target 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

  • Rate: 11.67 % (headline result)
  • quality gate defect rate gap to target: -5.92 points
  • Affected count: 14 count
  • Total count: 120 count
