Quality Escape Rate: Measure defects discovered by customers after internal quality controls.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Quality Escape Rate to answer this question: measure defects discovered by customers after internal quality controls? Enter Defects found internally, Defects found after delivery, Units delivered, and 1 other input; the calculator shows Quality escape rate. Try changing one number and watch what happens to Quality escape rate. The answer tells you Quality escape rate.
Age 15Explain it to a 15-year-oldConnect it to the formula
Use equivalent severity thresholds and reporting windows because low-frequency critical escapes can matter more than the count suggests. The rule is Quality escape rate = external defects ÷ total defects detected. Its input values are Defects found internally, Defects found after delivery, Units delivered, Average external defect cost, and the main result is Quality escape rate. Try changing one number and watch what happens to Quality escape rate.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Quality escape rate = external defects ÷ total defects detected, evaluated from Defects found internally, Defects found after delivery, Units delivered, Average external defect cost to produce Quality escape rate. Use equivalent severity thresholds and reporting windows because low-frequency critical escapes can matter more than the count suggests. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Measure defects discovered by customers after internal quality controls.
Why the business model works
Use equivalent severity thresholds and reporting windows because low-frequency critical escapes can matter more than the count suggests.
Inputs and operating assumptions
This model uses Defects found internally, Defects found after delivery, Units delivered, Average external defect cost. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Quality escape rate = external defects ÷ total defects detected
What the calculator produces
The primary output is Quality escape rate; it also exposes External defects per 10,000 units, Estimated external defect cost. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
