Critical Asset Downtime Risk with downtime consequence severity score of 5 score: a worked example

This worked example runs the critical asset downtime risk numbers for a tougher week than the baseline: downtime consequence severity score of 5 score instead of the typical 10 score. Score downtime risk for critical assets using consequence, likelihood of failure, and weakness of detection or mitigation controls.

The inputs for this scenario

  • Downtime consequence severity score: 5 score (the input this scenario stresses; the baseline uses 10)
  • Failure or downtime likelihood score: 5 score (held at the documented default)
  • Weakness of monitoring and contingency controls: 4 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Critical Asset Downtime Risk risk score = downtime consequence severity score × failure or downtime likelihood score × weakness of monitoring and contingency controls.
  • Critical Asset Downtime Risk risk score works out to 4.75 score at these inputs, and this is the headline figure for the scenario.
  • downtime consequence severity score works out to 5 score at these inputs.
  • failure or downtime likelihood score works out to 5 score at these inputs.
  • weakness of monitoring and contingency controls works out to 4 score at these inputs.

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 29.63% below the baseline at 4.75 score.
  • Use it during asset criticality reviews, FMEA-style assessments, or when prioritizing where to add condition monitoring and critical spares. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Critical Asset Downtime Risk risk score: 4.75 score (headline result)
  • downtime consequence severity score: 5 score
  • failure or downtime likelihood score: 5 score
  • weakness of monitoring and contingency controls: 4 score
