Asset Criticality Score with consequence severity if this asset fails of 23 score: a worked example

This scenario runs the asset criticality score calculation on the strong side: consequence severity if this asset fails of 23 score, with every other input held at its documented default. a maintenance or asset-management team needs to rank equipment for PM strategy, critical spares, condition monitoring, and replacement planning for a asset criticality review

The inputs for this scenario

  • Consequence severity if this asset fails: 23 score (raised for this scenario; the documented default is 9)
  • Likelihood of failure within the review window: 4 score (unchanged)
  • Difficulty of detecting the failure before it happens: 5 score (unchanged)

Working through the calculation

  • Applying the documented formula (Asset Criticality Score risk score = asset consequence severity score × asset failure likelihood score × failure detectability weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.85 score for asset criticality score risk score, the number this scenario is built around.
  • At this operating point the engine returns 23 score for asset consequence severity score.
  • At this operating point the engine returns 4 score for asset failure likelihood score.
  • At this operating point the engine returns 5 score for failure detectability weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where consequence severity if this asset fails sits at 9 score and the headline result is 6.25 score, this scenario comes in 89.6% above the baseline at 11.85 score.
  • Use it when building or re-ranking a PM program, setting spare-parts stocking levels, or running a maintenance risk review across a fleet of comparable assets. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
