Calibration Lab & Gauge Management worked example

Overdue Gauge Risk with overdue gauge impact severity of 15 score: a worked example

This scenario runs the overdue gauge risk calculation on the strong side: overdue gauge impact severity of 15 score, with every other input held at its documented default. Use it when overdue gauge risk in calibration lab and gauge management needs a defensible ranking against other calibration lab and gauge management risks for the next review.

The inputs for this scenario

  • Overdue gauge impact severity: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood of overdue gauge use: 4 score (unchanged)
  • Recall and lockout detection score: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Overdue gauge risk score = severity score × 0.40 + occurrence score × 0.35 + detection score × 0.25) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for overdue gauge risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for overdue gauge impact severity.
  • At this operating point the engine returns 4 score for likelihood of overdue use.
  • At this operating point the engine returns 3 score for recall and lockout detection score.

How this compares with the baseline

  • Against the tool's baseline example, where overdue gauge impact severity 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 to rank a list of overdue or soon-due gauges so recall effort goes to the riskiest assets 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
