Key idea: This is a stakeholder conflict question involving the Stepwise Evaluation Framework, balancing TCO against regulatory capacity constraints.
Step 1: Analyze the regulatory constraint. The ICU must maintain at least 75% ventilation capacity at all times.
Step 2: Evaluate Proposal Alpha. It requires a 2-day full shutdown, dropping capacity to 0%. The finance committee suggests transferring patients (an administrative workaround). However, transferring ICU patients is highly disruptive and risky, and the system itself fails the 75% capacity rule during installation.
Step 3: Evaluate Proposal Beta. It uses 4 modular units. If one fails, 3 remain (75% capacity). During phased installation, at least 3 units can remain operational, inherently satisfying the 75% regulation without administrative workarounds.
Step 4: Evaluate the finance committee's argument. They prioritize lower TCO but ignore the operational and regulatory reality of the 2-day shutdown. The higher TCO of Beta is a necessary investment to maintain continuous, compliant operations.
Step 5: Conclude. Option B correctly identifies that Beta's design inherently meets the regulatory constraint, making the finance committee's focus on TCO alone flawed.
Answer: B
