Warranty Risk with failure severity if attachment fails in field of 20 score: a worked example in construction machinery & attachments

This scenario runs the warranty risk calculation on the strong side: failure severity if attachment fails in field of 20 score, with every other input held at its documented default. prioritizing service, design, or manufacturing actions before field failures grow

The inputs for this scenario

  • Failure severity if attachment fails in field: 20 score (raised for this scenario; the documented default is 8)
  • Likelihood of this failure occurring: 5 score (unchanged)
  • Difficulty detecting failure before shipment: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Attachment warranty risk score = warranty severity score × weighted risk scale using occurrence and detection inputs) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.75 score for attachment warranty risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for warranty severity score.
  • At this operating point the engine returns 5 score for warranty occurrence score.
  • At this operating point the engine returns 4 score for warranty detection difficulty score.

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 80.67% above the baseline at 10.75 score.
  • Use it during design reviews, PPAP, and post-launch warranty triage to rank competing failure modes on the same 1-10 scoring table. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • attachment warranty risk score: 10.75 score (headline result)
