Work Order Aging Risk with asset and safety impact of aged work orders of 3.5 score: a worked example

This worked example runs the work order aging risk numbers for a tougher week than the baseline: asset and safety impact of aged work orders of 3.5 score instead of the typical 7 score. Score the risk from aging open work orders based on asset impact, recurrence of overdue work, and visibility of escalation controls.

The inputs for this scenario

  • Asset and safety impact of aged work orders: 3.5 score (the input this scenario stresses; the baseline uses 7)
  • Likelihood work orders exceed the age limit: 6 score (held at the documented default)
  • Weakness of escalation and review controls: 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Work Order Aging Risk risk score = asset and safety impact of aged work × likelihood work orders exceed age limit × weakness of escalation and review controls.
  • Work Order Aging Risk risk score works out to 4.75 score at these inputs, and this is the headline figure for the scenario.
  • asset and safety impact of aged work works out to 3.5 score at these inputs.
  • likelihood work orders exceed age limit works out to 6 score at these inputs.
  • weakness of escalation and review controls works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where asset and safety impact of aged work orders sits at 7 score and the headline result is 6.15 score, this scenario comes in 22.76% below the baseline at 4.75 score.
  • Use it during backlog reviews and maintenance risk assessments to rank which overdue work orders demand escalation first. 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

  • Work Order Aging Risk risk score: 4.75 score (headline result)
  • asset and safety impact of aged work: 3.5 score
  • likelihood work orders exceed age limit: 6 score
  • weakness of escalation and review controls: 5 score
