Wearable Medical Sensors worked example

Supplier Risk with component failure severity rating of 3 score: a worked example in wearable medical sensors

Here is what the math looks like when conditions slip. We hold every other input steady and drop component failure severity rating to 3 score, then walk the calculation through step by step. Estimate supplier risk for wearable medical sensors using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Component failure severity rating (patient impact): 3 score (the input this scenario stresses; the baseline uses 6)
  • Failure occurrence likelihood rating: 4 score (held at the documented default)
  • Incoming inspection detection rating: 3 score (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where component 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 component failure severity rating, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. RPN treats the three factors as equal and multiplicative, so a catastrophic severity of 10 can be masked by a low occurrence — always review high-severity items regardless of total score.
