# burnout (capacity)

maintenance sustained past the rate at which the maintaining capacity is restored, until that capacity leaves its own window.

## Emergence
**Emerges from:** [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [capacity](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-capacity.size), [potential](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-potential.capacity), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [rating](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-rating.evaluation)

**Through:** Maintenance continues beyond the restoration rate of capacity, causing gradual depletion until the capacity falls outside its viable range.

**Novel properties:**
- exhaustion of sustaining potential
- temporal overshoot of upkeep
- irreversible exit from functional range

## Examples
- California's 2021 energy grid strain during heatwaves exposed depleted reserves after months of underinvestment in maintenance and renewable integration. *(engineering)*
- The decline of Detroit’s municipal services by 2013, following decades of population loss and budget cuts, overwhelmed remaining operational capacity. *(institutions)*
- A nurse working 16 consecutive 12-hour shifts in an ICU reaches physical and cognitive exhaustion, impairing clinical judgment. *(everyday life)*
