Privileged Account Review Load at 46% owner follow up and remediation allowance: a worked example

Push owner follow up and remediation allowance up to 46% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning access recertification, audit evidence, and account cleanup for OT systems.

The inputs for this scenario

  • Privileged OT accounts to review: 360 accounts (unchanged)
  • Privileged account review rate: 32 accounts / hr (unchanged)
  • Owner follow up and remediation allowance: 46 % (raised for this scenario; the documented default is 40)

Working through the calculation

  • Applying the documented formula (Base privileged account review time = privileged OT accounts to review รท privileged account review rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 16.43 hr for required privileged account review time, the number this scenario is built around.
  • At this operating point the engine returns 11.25 hr for base privileged account review time.
  • At this operating point the engine returns 46 % for owner follow up and remediation allowance.
  • At this operating point the engine returns 32 pieces / min for privileged account review rate.

How this compares with the baseline

  • Against the tool's baseline example, where owner follow up and remediation allowance sits at 40% and the headline result is 15.75 hr, this scenario comes in 4.29% above the baseline at 16.43 hr.
  • It computes base review hours as accounts divided by review rate, then multiplies by an allowance factor to add owner follow-up and remediation time. 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.
