🎯 What does "die Effizienz" mean?

Die Effizienz (noun, feminine) describes the ratio of achieved benefit (Output) to the effort used (Input). It's about achieving a goal with the least possible use of resources (like time, money, materials, or energy). It's also referred to as Wirtschaftlichkeit (economic viability/cost-effectiveness) or Leistungsfähigkeit (performance capacity).

Essentially, *Effizienz* answers the question: "Are we doing things right?"

🚨 Important Distinction: *Effizienz* is not the same as Effektivität (effectiveness)! *Effektivität* means doing the right things to achieve a goal, regardless of the effort. *Effizienz*, on the other hand, means doing things right (i.e., with minimal effort).

• Example for Effizienz: A car that uses little fuel is *effizient*.
• Example for Effektivität: Reaching the destination with the car (no matter how much fuel it uses) is *effektiv*.

Mit wenig Müh', das Ziel erreichen,
Keine Ressource zu vergeuden, weichen.

Hat Zeit und Geld uns oft gebracht.
