Waste-to-Energy Equipment worked example

Supplier Risk with failure-impact severity rating of 3 score: a worked example in waste-to-energy equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop failure-impact severity rating to 3 score, then walk the calculation through step by step. Estimate supplier risk for waste-to-energy equipment using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Failure-impact severity rating: 3 score (the input this scenario stresses; the baseline uses 6)
  • Defect occurrence likelihood: 4 score (held at the documented default)
  • Incoming-inspection detection rating: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Supplier risk score = supplier risk severity score × supplier risk occurrence score × supplier risk detection score.
  • Supplier risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Supplier risk severity score works out to 3 score at these inputs.
  • Supplier risk occurrence score works out to 4 score at these inputs.
  • Supplier risk detection score works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where failure-impact severity rating sits at 6 score and the headline result is 4.55 score, this scenario comes in 26.37% below the baseline at 3.35 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to failure-impact severity rating, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Multiplicative RPN scores are non-linear and can mask a critical severity behind low occurrence — always review high-severity suppliers regardless of total score.
