Create a master key system design brief for a facility of [FacilitySquareMeters] sqm, specifying [MasterKeyLevels] levels (e.g., Grand Master, Master, Change). Identify [HighSecurityAreas] requiring restricted keyways and controlled duplication. Recommend a [LockManufacturer] platform compatible with existing hardware where feasible and outline rekey sequencing to minimize disruption. Include budgetary guardrails up to [BudgetCap] and a deployment horizon of [TimelineWeeks] weeks.
Output requirements:
Executive Overview (purpose, assumptions).
Key Hierarchy Model (textual tree, level definitions, access rules).
Bill of Materials (table: Location, Cylinder Type, Quantity, Notes).
Security Controls (table: Control, Rationale, Residual Risk).
Rollout Plan (phases with milestones and dependencies).
Communication Plan (audiences, messages, timing).
Success Criteria (measurable acceptance tests).
