Condition Monitoring Coverage at 65% condition monitoring coverage target: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop condition monitoring coverage target to 65%, then walk the calculation through step by step. Estimate the share of critical assets with active condition monitoring (vibration, temperature, current, oil) from the count of critical assets monitored against the total critical assets in the criticality register, against the program target.

The inputs for this scenario

  • Critical assets with active condition monitoring: 45 assets (held at the documented default)
  • Total critical assets: 60 assets (held at the documented default)
  • Condition monitoring coverage target: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Condition monitoring coverage = monitored critical assets ÷ total critical assets × 100.
  • Condition monitoring coverage works out to 75 % at these inputs, and this is the headline figure for the scenario.
  • Coverage gap to target works out to -10 points at these inputs.
  • Critical assets with condition monitoring works out to 45 count at these inputs.
  • Total critical assets works out to 60 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where condition monitoring coverage target sits at 90% and the headline result is 75 %, this scenario lands almost exactly on the baseline at 75 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to condition monitoring coverage target, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Coverage counts whether sensing exists, not whether the data is actually reviewed, alarmed correctly, or acted on — full coverage with ignored alerts still lets assets fail.

Results at a glance

  • Condition monitoring coverage: 75 % (headline result)
  • Coverage gap to target: -10 points
  • Critical assets with condition monitoring: 45 count
  • Total critical assets: 60 count
