- average warranty cost per claim or at-risk unit: Include service parts, labor, freight, handling, replacement units, call center support, and customer concessions.
- expected warranty claim occurrence: Use the expected claim percentage from history, reliability testing, early-life returns, or field quality data.
- fixed warranty campaign and claims administration cost: Include service bulletin support, claims processing, dealer or retailer handling, root-cause work, and reserve true-up.
How to use the result
- Use it to support finance accruals, compare reliability risks, evaluate supplier issues, and decide whether added inspection or design changes are justified.
