TL;DR: Unsensored components in decades-old military platforms create readiness blind spots, prolong diagnostics and increase mission risk, according to Shift5. Predictive maintenance has to extend beyond directly instrumented systems if degradation is to surface before failure.
Editorial analysis by NHI Mgmt Group, based on content published by Shift5: “Unlocking Predictive Maintenance for Unsensored Systems”.
Key questions
Q: Why do blind spots in operational monitoring increase mission or business risk?
A: Blind spots delay detection, which extends the time between deterioration and intervention.
Q: What are the signs that predictive maintenance is missing important failure modes?
A: Common signs include repeated surprise failures, long diagnostic cycles, and sensor data that looks healthy even as performance declines.
Q: What breaks when critical assets are monitored only through proxy telemetry?
A: Proxy telemetry can reveal drift, but it cannot guarantee that every failure mode is visible.
Practitioner guidance
- Define the monitored boundary for every critical system Inventory which components, identities or assets are directly sensed and which depend on proxy inference, then document the blind spots that remain outside native coverage.
- Use proxy telemetry to rank degradation risk Correlate surrounding sensor behaviour into a drift model so maintainers can prioritise inspection where the evidence suggests hidden deterioration is most likely.
- Tie anomaly thresholds to response workflows Convert near real-time alerts into named maintenance actions, ownership and escalation paths so a signal leads to repair, replacement or deeper forensic review.
Bottom line: The article shows that unsensored components create blind spots that can delay maintenance and increase mission risk.

Readiness blind spots are a governance problem, not just a telemetry problem. The article shows that systems can appear observable while critical components remain effectively invisible. That is the same structural weakness seen in identity estates where teams monitor the managed surface but not the full set of machine or delegated identities. The named concept here is observability coverage debt: the gap between what a programme believes it can see and what it can actually govern. Practitioners should treat coverage as a control boundary, not a reporting convenience.
A question worth separating out:
Q: How should teams balance direct sensing with inferred monitoring?
A: Use direct sensing for components that materially affect safety, availability or control, and use inferred monitoring where the physics or cost of direct instrumentation makes that impractical. The decision should be based on criticality, not convenience. A mature programme treats inferred signals as decision support, not as a blanket substitute for sensor coverage.
