# window of opportunity (threshold)

*Ordinarily means:* a short period when conditions are right to do something

a brief drift in a parameter that temporarily places it between two walls, allowing an action that was previously impossible

- Computed level: L18 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: opportunity  ·  Arena: strategic.action

## Emergence
**Emerges from:** [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), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end)

**Through:** emergence.components

**Novel properties:**
- temporal.opening
- action.enabling

## Examples
- In 2012, the Higgs boson appeared in LHC collisions when energy levels briefly crossed 125 GeV between detection thresholds. *(physics)*
- The 2008 financial crisis allowed rapid passage of the Dodd-Frank Act before political resistance reformed. *(institutions)*
- The New Horizons probe relayed Pluto data in 2015 when its trajectory briefly placed it within signal range of Earth. *(engineering)*
