Rail Signaling & Wayside Equipment worked example

Compliance Documentation with impact of a documentation gap on approval of 15 score: a worked example in rail signaling & wayside equipment

This scenario runs the compliance documentation calculation on the strong side: impact of a documentation gap on approval of 15 score, with every other input held at its documented default. Use it when compliance documentation in rail signaling and wayside equipment needs a defensible ranking against other rail signaling and wayside equipment risks for the next review.

The inputs for this scenario

  • Impact of a documentation gap on approval: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood a compliance record is missing or wrong: 4 score (unchanged)
  • Chance a records audit misses the gap: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Compliance documentation risk score = compliance documentation severity score × compliance documentation occurrence score × compliance documentation detection score) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for compliance documentation risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for compliance documentation severity score.
  • At this operating point the engine returns 4 score for compliance documentation occurrence score.
  • At this operating point the engine returns 3 score for compliance documentation detection score.

How this compares with the baseline

  • Against the tool's baseline example, where impact of a documentation gap on approval sits at 6 score and the headline result is 4.55 score, this scenario comes in 79.12% above the baseline at 8.15 score.
  • Use it ahead of an independent safety assessment, design review gate, or handover to flag which record sets need the most remediation effort. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
