Graphite, Anode & Battery Materials Processing worked example

Supplier Risk with supplier issue severity score of 20 score: a worked example in graphite, anode & battery materials processing

What does the result look like when supplier issue severity score reaches 20 score? The full calculation is worked below with real intermediate numbers. Use it when procurement, quality, and operations need a consistent score for supplier issues such as impurity ppm drift, PSD mismatch, late deliveries, documentation gaps, or unqualified lots.

The inputs for this scenario

  • Supplier issue severity score: 20 score (raised for this scenario; the documented default is 8)
  • Supplier issue occurrence score: 5 score (unchanged)
  • Incoming-control detection score: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Supplier risk score = supplier issue severity score × supplier issue occurrence score × incoming-control detection score) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.75 score for supplier risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for supplier issue severity score.
  • At this operating point the engine returns 5 score for supplier issue occurrence score.
  • At this operating point the engine returns 4 score for incoming-control detection score.

How this compares with the baseline

  • Against the tool's baseline example, where supplier issue severity score 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.
  • A figure at this level is achievable when supplier issue severity score is genuinely sustained, not just peaked for a shift. Like any RPN-style score it is ordinal, not absolute — the multiplication can mask a critical severity behind good detection, so always review high-severity items regardless of total score.
