Productiviteit is de kwantiteit van het werk dat een team, bedrijf of individu levert, terwijl bij efficiëntie de focus ligt op kwaliteit. Efficiëntie en productiviteit zijn bij tijd en wijle ook concurrenten van elkaar. Een verhoogde productiviteit kan ten koste gaan van efficiëntie, terwijl meer efficiëntie soms ook de productiviteit remt.
