eficiencia

efficiency

noun eh-fee-SYEN-syah Rare

Usage Note

Eficiencia is about achieving results with minimal waste — closer to English 'efficiency' than eficacia, which stresses effectiveness (getting the right outcome regardless of cost). In engineering and business contexts the two words are often contrasted: eficacia = does it work? eficiencia = does it work economically?

Examples

"La eficiencia de la máquina aumentó un veinte por ciento."

Natural Translation

The machine's efficiency increased by twenty percent.
