Hose, Tubing & Fluid Conveyance Products worked example

Warranty Exposure with field-failure severity of 18 score: a worked example in hose, tubing & fluid conveyance products

What does the result look like when field-failure severity reaches 18 score? The full calculation is worked below with real intermediate numbers. Use it when reviewing warranty risk for a hose assembly product, ranking claims by risk priority, or deciding whether a design or process change is justified.

The inputs for this scenario

  • Field-failure severity (impact if it fails): 18 score (raised for this scenario; the documented default is 7)
  • Failure occurrence likelihood: 3 score (unchanged)
  • Detection difficulty before shipment: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Warranty exposure score = severity x 0.40 + occurrence x 0.35 + detection x 0.25) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.25 score for warranty exposure score, the number this scenario is built around.
  • At this operating point the engine returns 18 score for failure severity score.
  • At this operating point the engine returns 3 score for failure occurrence score.
  • At this operating point the engine returns 4 score for detection difficulty score.

How this compares with the baseline

  • Against the tool's baseline example, where field-failure severity sits at 7 score and the headline result is 4.85 score, this scenario comes in 90.72% above the baseline at 9.25 score.
  • A figure at this level is achievable when field-failure severity is genuinely sustained, not just peaked for a shift. The 1-10 inputs are judgment-based, so the score is only as good as your scoring discipline — calibrate the scales against real field-return data, not gut feel.
