Leistung
Leistung can be translated as performance, work achieved, or productivity. The term is personalized, referring to a person’s individual achievement (as opposed to a word like Arbeit, which means “work.”)
In the Nazi context, the word work was functionally replaced by Leistung as a means of exaggerating its significance.
