Design a 90-minute tabletop exercise simulating [ScenarioType] (e.g., VIP tailgating into restricted lab) involving [ParticipantsRoles]. Timebox to [TimeboxMinutes] and align with objectives [Objectives] measured against [EvaluationCriteria]. Output format: (1) Exercise plan (scope, assumptions, rules of engagement). (2) Timeline with injects every 10–15 minutes (information cards, decisions required, artifacts provided). (3) Roles & responsibilities matrix (players, controllers, observers). (4) Communications drill (radio/phone/email templates). (5) Evaluation checklist and scoring guide per objective. (6) After-Action Report template (Findings, Strengths, Improvement Actions, Owners, Due Dates). Incorporate decision pressure, ambiguity, and regulator/media triggers to test escalation discipline.
