Warranty Exposure with field failure severity of 3 score: a worked example in heat exchanger, coil & radiator manufacturing

Suppose field failure severity falls to 3 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Score warranty exposure for heat exchangers, coils, radiators, condensers, evaporators, and oil coolers using severity, occurrence, and detection ratings.

The inputs for this scenario

  • Field failure severity: 3 score (the input this scenario stresses; the baseline uses 6)
  • Expected warranty occurrence: 4 score (held at the documented default)
  • Pre-shipment detection risk: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Warranty exposure score = field failure severity × 0.40 + expected warranty occurrence × 0.35 + pre-shipment detection risk × 0.25.
  • Warranty exposure score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Field failure severity works out to 3 score at these inputs.
  • Expected warranty occurrence works out to 4 score at these inputs.
  • Pre-shipment detection risk works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where field failure severity sits at 6 score and the headline result is 4.55 score, this scenario comes in 26.37% below the baseline at 3.35 score.
  • It blends field failure severity, expected warranty occurrence and pre-shipment detection risk into a single 0-10 weighted warranty exposure score. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Warranty exposure score: 3.35 score (headline result)
  • Field failure severity: 3 score
  • Expected warranty occurrence: 4 score
  • Pre-shipment detection risk: 3 score
