Construction Machinery & Attachments worked example

Warranty Risk with failure severity if attachment fails in field of 4 score: a worked example in construction machinery & attachments

Suppose failure severity if attachment fails in field falls to 4 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Score warranty risk for construction machinery attachments and field failures.

The inputs for this scenario

  • Failure severity if attachment fails in field: 4 score (the input this scenario stresses; the baseline uses 8)
  • Likelihood of this failure occurring: 5 score (held at the documented default)
  • Difficulty detecting failure before shipment: 4 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Attachment warranty risk score = warranty severity score × weighted risk scale using occurrence and detection inputs.
  • attachment warranty risk score works out to 4.35 score at these inputs, and this is the headline figure for the scenario.
  • warranty severity score works out to 4 score at these inputs.
  • warranty occurrence score works out to 5 score at these inputs.
  • warranty detection difficulty score works out to 4 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where failure severity if attachment fails in field sits at 8 score and the headline result is 5.95 score, this scenario comes in 26.89% below the baseline at 4.35 score.
  • It combines a severity score with a weighted blend of occurrence and detection scores to produce a single attachment warranty risk number for one failure mode. 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

  • attachment warranty risk score: 4.35 score (headline result)
  • warranty severity score: 4 score
  • warranty occurrence score: 5 score
  • warranty detection difficulty score: 4 score
