Supplier Quality, Development & Audits worked example

Supplier Scorecard with failure severity rating of 3 score: a worked example in supplier quality, development & audits

Here is what the math looks like when conditions slip. We hold every other input steady and drop failure severity rating to 3 score, then walk the calculation through step by step. Estimate supplier scorecard for supplier quality, development and audits 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 severity rating (1-10): 3 score (the input this scenario stresses; the baseline uses 6)
  • Defect occurrence likelihood (1-10): 4 score (held at the documented default)
  • Detection difficulty rating (1-10): 3 score (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where failure 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 severity rating, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. RPN is ordinal, not linear - a score of 120 is not literally twice as risky as 60, and identical products can come from very different rating combinations, so always inspect the underlying severity, occurrence, and detection values.
