Maintenance Backlog measures the volume of deferred upkeep required to keep infrastructure functional.
Backlog is decay stored as debt.
It compounds.
When backlog rises faster than repair capacity, breakdowns become inevitable.
What This Sensor Measures
Maintenance Backlog measures:
Deferred maintenance volume
Backlog growth rate
Aging asset percentage
Emergency repair frequency
Repair cost inflation over time
How to Read This Sensor
Healthy signal
Backlog stable or shrinking
Emergency repairs are rare
Costs are predictable
Failures decrease over time
Upgrades happen alongside upkeep
Danger signal
Backlog grows continuously
Emergency repairs dominate schedules
Costs rise rapidly
Breakdowns recur
Upgrades are delayed because maintenance consumes resources
Thresholds
Level 1: Controlled backlog
Stable backlog, predictable repairs
Level 2: Mild backlog
Some accumulation, manageable
Level 3: Rising backlog
Decay becomes visible, failures increase
Level 4: Backlog crisis
Emergency repairs dominate, downtime rises
Level 5: Backlog collapse
Failure rate outruns repair capacity, brittleness accelerates
Minimum Viable Test
Track 6 months:
Is backlog growing or shrinking?
If it grows even during high repair effort, repair capacity is insufficient.

Canonical Statement
Maintenance Backlog measures stored decay. If backlog grows faster than repair, infrastructure becomes brittle and failures compound.
