Supplier Risk Score with severity of a supplier failure of 20 score: a worked example in supply chain & procurement

What does the result look like when severity of a supplier failure reaches 20 score? The full calculation is worked below with real intermediate numbers. Use it when supplier risk in supply chain and procurement needs a defensible ranking against other supply chain and procurement risks for the next review.

The inputs for this scenario

  • Severity of a supplier failure (1-10): 20 score (raised for this scenario; the documented default is 8)
  • Likelihood the failure occurs (1-10): 6 score (unchanged)
  • Difficulty detecting it before impact (1-10): 7 score (unchanged)

Working through the calculation

  • Applying the documented formula (Weighted score = severity × 0.40 + occurrence × 0.35 + detection × 0.25) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.85 score for supplier risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for supplier risk severity score.
  • At this operating point the engine returns 6 score for supplier risk occurrence score.
  • At this operating point the engine returns 7 score for supplier risk detection score.

How this compares with the baseline

  • Against the tool's baseline example, where severity of a supplier failure sits at 8 score and the headline result is 7.05 score, this scenario comes in 68.09% above the baseline at 11.85 score.
  • A figure at this level is achievable when severity of a supplier failure is genuinely sustained, not just peaked for a shift. The weights are a convention, not a law of physics; a supplier that is catastrophic but rare can still score moderate, so always eyeball a severity of 9-10 regardless of the composite.
