Hose, Tubing & Fluid Conveyance Products worked example

Warranty Exposure with field-failure severity of 3.5 score: a worked example in hose, tubing & fluid conveyance products

Here is what the math looks like when conditions slip. We hold every other input steady and drop field-failure severity to 3.5 score, then walk the calculation through step by step. Score warranty exposure risk for a hose or tubing assembly product from failure severity, occurrence likelihood, and detection difficulty.

The inputs for this scenario

  • Field-failure severity (impact if it fails): 3.5 score (the input this scenario stresses; the baseline uses 7)
  • Failure occurrence likelihood: 3 score (held at the documented default)
  • Detection difficulty before shipment: 4 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Warranty exposure score = severity x 0.40 + occurrence x 0.35 + detection x 0.25.
  • Warranty exposure score works out to 3.45 score at these inputs, and this is the headline figure for the scenario.
  • Failure severity score works out to 3.5 score at these inputs.
  • Failure occurrence score works out to 3 score at these inputs.
  • Detection difficulty score works out to 4 score at these inputs.

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 28.87% below the baseline at 3.45 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to field-failure severity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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.

Results at a glance

  • Warranty exposure score: 3.45 score (headline result)
  • Failure severity score: 3.5 score
  • Failure occurrence score: 3 score
  • Detection difficulty score: 4 score
