Bend Radius Risk with bend-radius severity score of 3.5 score: a worked example

This worked example runs the bend radius risk numbers for a tougher week than the baseline: bend-radius severity score of 3.5 score instead of the typical 7 score. Score bend-radius risk for fiber cable or optical interconnect routing from severity, occurrence, and detection ratings.

The inputs for this scenario

  • Bend-radius severity score: 3.5 score (the input this scenario stresses; the baseline uses 7)
  • Bend-radius occurrence score: 4 score (held at the documented default)
  • Bend-radius detection difficulty score: 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Bend-radius risk score = severity × 0.40 + occurrence × 0.35 + detection × 0.25.
  • Weighted bend-radius risk score works out to 4.05 score at these inputs, and this is the headline figure for the scenario.
  • Bend-radius severity score works out to 3.5 score at these inputs.
  • Bend-radius occurrence score works out to 4 score at these inputs.
  • Detection weakness score works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where bend-radius severity score sits at 7 score and the headline result is 5.45 score, this scenario comes in 25.69% below the baseline at 4.05 score.
  • Use it during fiber routing design reviews, strain-relief DFMEA, or when triaging field bend complaints to prioritize fixes. 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

  • Weighted bend-radius risk score: 4.05 score (headline result)
  • Bend-radius severity score: 3.5 score
  • Bend-radius occurrence score: 4 score
