Traceability, Serialization & Lot Genealogy worked example

Traceability Gap Score with consequence severity of the traceability gap of 15 score: a worked example

This scenario runs the traceability gap score calculation on the strong side: consequence severity of the traceability gap of 15 score, with every other input held at its documented default. Use it when traceability gap in traceability, serialization and lot genealogy needs a defensible ranking against other traceability, serialization and lot genealogy risks for the next review.

The inputs for this scenario

  • Consequence severity of the traceability gap: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood the gap occurs: 4 score (unchanged)
  • Ability to detect the gap before impact: 3 score (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where consequence severity of the traceability gap 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 when triaging multiple traceability or serialization weaknesses and you need a defensible ranking of what to fix first. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Traceability gap risk score: 8.15 score (headline result)
  • Traceability gap severity score: 15 score
  • Traceability gap occurrence score: 4 score
