Why alarm half-life matters more than alarm count

Operators in mission-critical floors often inherit dashboards tuned for a different era. When every sensor can speak, the instinct is to chase a lower alarm count. In practice, the more durable signal is alarm half-life: how long a condition persists before it is understood, mitigated, or escalated with evidence.

We recommend pairing half-life with a simple acknowledgement policy so technicians are not punished for leaving alarms open while investigating. The goal is to reward curiosity and penalize only silent ageing. During our BMS Alarm Triage lab, cohorts practice clustering bursts and narrating hypotheses before clicking acknowledge.

If your organization still bonuses teams on “cleared alarms per hour,” consider reframing incentives around documented outcomes instead. Half-life drops naturally when narratives improve, even if raw counts stay noisy during migrations.
