Outdoor Power Equipment worked example
Supplier Risk with failure severity score of 3 score: a worked example in outdoor power equipment
This worked example runs the supplier risk numbers for a tougher week than the baseline: failure severity score of 3 score instead of the typical 6 score. Score supplier risk for engine, battery, and casting components by multiplying severity, occurrence, and detection into one ranking number.
The inputs for this scenario
- Failure severity score: 3 score (the input this scenario stresses; the baseline uses 6)
- Failure occurrence score: 4 score (held at the documented default)
- Detection difficulty score: 3 score (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Supplier risk score = severity score × occurrence score × detection score.
- Supplier risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
- Severity score works out to 3 score at these inputs.
- Occurrence score works out to 4 score at these inputs.
- 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 score 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.
- Use it during supplier qualification, annual reviews, or whenever a quality escape forces you to re-rate a vendor. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
