Telecommunications & Network Hardware Manufacturing worked example

Supplier Component Risk with failure severity rating of 3 score: a worked example

This worked example runs the supplier component risk numbers for a tougher week than the baseline: failure severity rating of 3 score instead of the typical 6 score. Estimate supplier component risk for telecommunications and network hardware manufacturing 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: 3 score (the input this scenario stresses; the baseline uses 6)
  • Defect occurrence likelihood: 4 score (held at the documented default)
  • Detection difficulty rating: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Supplier component risk score = supplier component risk severity score × supplier component risk occurrence score × supplier component risk detection score.
  • Supplier component risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Supplier component risk severity score works out to 3 score at these inputs.
  • Supplier component risk occurrence score works out to 4 score at these inputs.
  • Supplier component risk 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.
  • Use it during supplier qualification, incoming-inspection planning, or a PPAP review to prioritize which components get the most scrutiny. 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.

Results at a glance

  • Supplier component risk score: 3.35 score (headline result)
  • Supplier component risk severity score: 3 score
  • Supplier component risk occurrence score: 4 score
