Best practice
Use "running at full capacity" to clearly indicate that a system, factory, or organization is operating at its maximum possible level. This is particularly useful when reporting on production levels, resource utilization, or economic performance. For better clarity, consider quantifying the capacity, such as "The factory is running at full capacity, producing 1,000 units per day".
Common error
While "running at full capacity" is a clear indicator of peak operation, avoid using it without providing context. Instead of simply stating that something is "running at full capacity", explain what that capacity entails. For example, clarify what metrics define "full capacity" (e.g., production volume, patient throughput) to avoid ambiguity.
