Cyber Drill Labor Load at 57% preparation and follow up allowance: a worked example

Push preparation and follow up allowance up to 57% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning incident response drills, backup recovery exercises, or plant cyber tabletop events.

The inputs for this scenario

  • Cyber drill work items or participant sessions: 72 items (unchanged)
  • Drill completion rate: 6 items / hr (unchanged)
  • Preparation and follow up allowance: 57 % (raised for this scenario; the documented default is 50)

Working through the calculation

  • Applying the documented formula (Base cyber drill labor time = cyber drill work items or participant sessions รท drill completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 18.84 hr for required cyber drill labor time, the number this scenario is built around.
  • At this operating point the engine returns 12 hr for base cyber drill labor time.
  • At this operating point the engine returns 57 % for preparation and follow up allowance.
  • At this operating point the engine returns 6 pieces / min for drill completion rate.

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 4.67% above the baseline at 18.84 hr.
  • It computes the total labor hours for a cyber drill by dividing work items or sessions by the completion rate, then adding a preparation-and-follow-up allowance. 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.

Results at a glance

  • Required cyber drill labor time: 18.84 hr (headline result)
  • Base cyber drill labor time: 12 hr
  • Preparation and follow up allowance: 57 %
  • Drill completion rate: 6 pieces / min
