Cyber Drill Labor Load at 36% preparation and follow up allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop preparation and follow up allowance to 36%, then walk the calculation through step by step. Estimate labor hours required for an OT cyber drill or tabletop exercise using participant work items, completion rate, and allowance.

The inputs for this scenario

  • Cyber drill work items or participant sessions: 72 items (held at the documented default)
  • Drill completion rate: 6 items / hr (held at the documented default)
  • Preparation and follow up allowance: 36 % (the input this scenario stresses; the baseline uses 50)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base cyber drill labor time = cyber drill work items or participant sessions รท drill completion rate.
  • Required cyber drill labor time works out to 16.32 hr at these inputs, and this is the headline figure for the scenario.
  • Base cyber drill labor time works out to 12 hr at these inputs.
  • Preparation and follow up allowance works out to 36 % at these inputs.
  • Drill completion rate works out to 6 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where preparation and follow up allowance sits at 50% and the headline result is 18 hr, this scenario comes in 9.33% below the baseline at 16.32 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to preparation and follow up allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a steady completion rate; complex multi-team injects or scenarios with live system interaction can run slower, so validate the rate against your actual exercise history.

Results at a glance

  • Required cyber drill labor time: 16.32 hr (headline result)
  • Base cyber drill labor time: 12 hr
  • Preparation and follow up allowance: 36 %
  • Drill completion rate: 6 pieces / min
