The square-root staffing principle is a fundamental result in queueing theory that ensures optimal staffing levels in multi-server systems. It states that the amount of excess capacity required scales with the square root of the system size, allowing for efficient resource allocation.

### Challenges
|
|
- Assumes homogeneous service rates and arrival processes.
|
|
- May not account for variability in real-world systems.
|
|
|
|
### Evidence
|
|
- Proven through mathematical derivation and supported by empirical studies.
|
|
|
|
### Cross-references
|
|
- Related to QED regimes and variance pooling. |
