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
