Critical Asset Downtime Risk with downtime consequence severity score of 25 score: a worked example

Push downtime consequence severity score up to 25 score and the picture changes. This example computes every intermediate figure at that operating point. a maintenance or asset-management team needs to prioritize condition monitoring, critical spares, PM changes, and contingency planning for a critical asset risk review

The inputs for this scenario

  • Downtime consequence severity score: 25 score (raised for this scenario; the documented default is 10)
  • Failure or downtime likelihood score: 5 score (unchanged)
  • Weakness of monitoring and contingency controls: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Critical Asset Downtime Risk risk score = downtime consequence severity score × failure or downtime likelihood score × weakness of monitoring and contingency controls) to the inputs above produces each figure below.
  • At this operating point the engine returns 12.75 score for critical asset downtime risk risk score, the number this scenario is built around.
  • At this operating point the engine returns 25 score for downtime consequence severity score.
  • At this operating point the engine returns 5 score for failure or downtime likelihood score.
  • At this operating point the engine returns 4 score for weakness of monitoring and contingency controls.

How this compares with the baseline

  • Against the tool's baseline example, where downtime consequence severity score sits at 10 score and the headline result is 6.75 score, this scenario comes in 88.89% above the baseline at 12.75 score.
  • It computes a single downtime risk score as the product of consequence severity, failure likelihood, and control weakness on a common scale. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
