OT Vulnerability Backlog at 61% target remediation capacity utilization: a worked example

Suppose target remediation capacity utilization falls to 61%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure OT vulnerability backlog load against available remediation capacity and a target utilization level.

The inputs for this scenario

  • OT vulnerability remediation backlog: 420 hours (held at the documented default)
  • Available OT remediation capacity: 520 hours (held at the documented default)
  • Target remediation capacity utilization: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: OT vulnerability backlog utilization = OT vulnerability remediation backlog รท available OT remediation capacity.
  • OT vulnerability backlog utilization works out to 80.77 % at these inputs, and this is the headline figure for the scenario.
  • OT vulnerability backlog utilization gap works out to -19.77 points at these inputs.
  • OT vulnerability remediation backlog works out to 420 hours at these inputs.
  • Available OT remediation capacity works out to 520 hours at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target remediation capacity utilization sits at 85% and the headline result is 80.77 %, this scenario lands almost exactly on the baseline at 80.77 %.
  • It computes the ratio of OT vulnerability remediation backlog hours to available remediation capacity, plus the gap to your target utilization. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • OT vulnerability backlog utilization: 80.77 % (headline result)
  • OT vulnerability backlog utilization gap: -19.77 points
  • OT vulnerability remediation backlog: 420 hours
  • Available OT remediation capacity: 520 hours

Run it with your numbers
