Industrial Cybersecurity & OT Risk calculator

Cyber Drill Labor Load Calculator

Use this calculator to estimate labor load for an OT cyber drill. It fits tabletop exercises, backup restore drills, communications exercises, incident response rehearsals, and recovery validation sessions involving operations, controls, IT, security, and vendors.

What this calculator does

  • Estimate labor hours required for an OT cyber drill or tabletop exercise using participant work items, completion rate, and allowance.
  • Use it when planning incident response drills, backup recovery exercises, or plant cyber tabletop events.
  • The result estimates labor hours needed for the drill scope.

Formula used

  • Base cyber drill labor time = cyber drill work items or participant sessions ÷ drill completion rate
  • Required cyber drill labor time = base cyber drill labor time × allowance factor

Inputs explained

  • Cyber drill work items or participant sessions: Count participants, exercise injects, recovery steps, scenario work packages, or follow up items included in the drill.
  • Drill completion rate: Use a realistic facilitation or review rate based on prior tabletop, restore, or incident response exercises.
  • Preparation and follow up allowance: Add time for planning, briefings, evidence collection, action tracking, lessons learned, and management review.

How to use the result

  • Use it to schedule participants, justify preparation time, and plan remediation follow up.
  • It does not evaluate drill quality or replace an approved response exercise plan.

Common questions

  • What is the cyber drill labor load calculator for? It estimates labor required to plan, run, and follow up an OT cyber drill.
  • What information should I enter? Use work item count, completion rate, and preparation or follow up allowance.
  • What does the result tell me? The result helps schedule tabletop exercises and recovery drills without underestimating plant labor.
  • When is the result only an estimate? It is only an estimate when participant count, scenario complexity, or follow up findings change.
