Part Distortion Risk with severity of distortion if it occurs of 3 score: a worked example

Suppose severity of distortion if it occurs falls to 3 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Score part distortion risk from severity, occurrence, and detection risk for heat treated parts.

The inputs for this scenario

  • Severity of distortion if it occurs: 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood distortion occurs this run: 4 score (held at the documented default)
  • Difficulty of detecting distortion before shipment: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Part Distortion Risk score = distortion impact severity × 0.40 + distortion occurrence likelihood × 0.35 + distortion detection risk × 0.25.
  • Part Distortion Risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Distortion impact severity works out to 3 score at these inputs.
  • Distortion occurrence likelihood works out to 4 score at these inputs.
  • Distortion detection risk works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where severity of distortion if it occurs 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.
  • It blends a severity, occurrence, and detection score into a single weighted distortion-risk number, leaning hardest on how bad the outcome is and least on how likely you are to catch it. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Part Distortion Risk score: 3.35 score (headline result)
  • Distortion impact severity: 3 score
  • Distortion occurrence likelihood: 4 score
  • Distortion detection risk: 3 score
