Compliance Documentation with impact of a documentation gap on approval of 3 score: a worked example in rail signaling & wayside equipment

Suppose impact of a documentation gap on approval 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. Estimate compliance documentation for rail signaling and wayside equipment using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Impact of a documentation gap on approval: 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood a compliance record is missing or wrong: 4 score (held at the documented default)
  • Chance a records audit misses the gap: 3 score (held at the documented default)

Working through the calculation

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

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 26.37% below the baseline at 3.35 score.
  • It multiplies the severity, occurrence likelihood and detection difficulty of a compliance-documentation defect into one Risk Priority Number. 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

  • Compliance documentation risk score: 3.35 score (headline result)
  • Compliance documentation severity score: 3 score
  • Compliance documentation occurrence score: 4 score
  • Compliance documentation detection score: 3 score
