Sell condition monitoring where a signal can become a work order.

Gross benefit = potential units × economic unit value × realized share.

Full year-one cost = full upfront deployment + annual operating cost. Net = benefit − full cost. Year-one ROI = net ÷ full cost × 100. Each cost is subtracted once.

Simple upfront payback = upfront cost ÷ (annual benefit − annual operating cost) × 12 months, only if annual net benefit is positive. It assumes steady annual realization, not a discounted cash-flow forecast. Year-one break-even units = full year-one cost ÷ realized unit value.

NIST describes predictive maintenance as analogous to condition-based maintenance, initiated from failure predictions using observed data such as temperature, noise and vibration. DOE describes measurement detecting the onset of system degradation and allowing causal stressors to be addressed before significant deterioration. For a buyer pilot, establish a baseline and track actual maintenance hours reassigned to planned or other productive work; separate planned, reactive and condition-triggered activity. NIST's 2025 systematic review reports heterogeneous performance measures, economic analyses and uncertainty analysis, so do not treat a single case or estimate as a transferable result.

These sources explain the economic mechanism and measurement—not Alma Hunter performance:

• Manufacturing Machinery Maintenance — National Institute of Standards and Technology — Defines predictive maintenance as analogous to condition-based maintenance and initiated from failure predictions using observed data such as temperature, noise and vibration; also describes the metrics and estimates used in its manufacturing analysis.
• Operations & Maintenance Best Practices Guide, Release 3.0 — U.S. Department of Energy — Chapter 5 defines predictive maintenance around measurements that detect system degradation and distinguishes it from time-based preventive maintenance; lists preemptive corrective action and decreased equipment or process downtime as potential advantages, not guarantees.
• Comprehensive evaluations of condition monitoring-based technologies in industrial maintenance: A systematic review — NIST — 2025 review of 42 eligible studies reports that evaluations can lack detail and are difficult to compare because economic analyses, performance measures and uncertainty analyses are heterogeneous.
