Municipal Waste Sorting Equipment worked example

Supplier Risk with failure severity score of 18 score: a worked example in municipal waste sorting equipment

This scenario runs the supplier risk calculation on the strong side: failure severity score of 18 score, with every other input held at its documented default. Use it when ranking sorter, baler, conveyor, or spare parts suppliers for a procurement review or qualification audit.

The inputs for this scenario

  • Failure severity score: 18 score (raised for this scenario; the documented default is 7)
  • Occurrence likelihood score: 4 score (unchanged)
  • Detection difficulty score: 5 score (unchanged)

Working through the calculation

  • Applying the documented formula (Supplier risk score = severity score x occurrence score x detection score) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.85 score for supplier risk score (rpn), the number this scenario is built around.
  • At this operating point the engine returns 18 score for severity score.
  • At this operating point the engine returns 4 score for occurrence score.
  • At this operating point the engine returns 5 score for detection score.

How this compares with the baseline

  • Against the tool's baseline example, where failure severity score sits at 7 score and the headline result is 5.45 score, this scenario comes in 80.73% above the baseline at 9.85 score.
  • Use it to triage suppliers and components for audits, dual sourcing, and incoming inspection during supplier qualification and periodic reviews. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
