Perform a comparative cost–benefit analysis for rekeying versus full hardware replacement across [NumberOfCylinders] cylinders. Use an average labor rate of [AvgLaborRate] and replacement cost per lock of [ReplacementCostPerLock]. Quantify operational downtime at [DowntimeCostPerHour] per hour and incorporate a breach likelihood of [RiskProbability] per annum. Include a recommendation over [Timeframe] with sensitivity testing.
Output requirements:
Assumptions & Inputs (table).
Scenario Analysis (Rekey, Hybrid, Replace) with 5-year TCO and payback.
Risk-Adjusted Cost Model (expected loss, control efficacy).
Sensitivity Table (vary labor ±20%, breach probability ±50%).
Executive Recommendation (bulleted with rationale).
Implementation Considerations (procurement, lead times, training).
