Mining Vehicle & Underground Equipment worked example

Supplier Risk Score with severity of supplier failure on equipment build of 3 score: a worked example in mining vehicle & underground equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop severity of supplier failure on equipment build to 3 score, then walk the calculation through step by step. Estimate supplier risk for mining vehicle and underground 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

  • Severity of supplier failure on equipment build: 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood the supplier defect occurs: 4 score (held at the documented default)
  • Chance defect is caught before installation: 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 severity of supplier failure on equipment build 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 severity of supplier failure on equipment build, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The score is ordinal, not absolute. Equal scores can hide a high-severity item that always deserves attention regardless of how rarely it occurs or how easily it is caught.

Results at a glance

  • Supplier risk score: 3.35 score (headline result)
