    • Measure of product improvement
    • Represents output relative to input

  • What is the formula of single factor productivity?
    See picture.
    For example:
    • If 1000 hamburgers are produced using 500 hours of labor

  • What is the formula of multi factor productivity?
    See picture
    Multi factor: niet op basis van 1 factor, maar op basis van een hele set factoren.
    Hoe kun je een arbeidsuur nou vergelijken met plakje kaas? Bv door om te rekenen in geld.
    Zie ook example onderaan. Zou betekenen 10 euro kostprijs voor die hamburger, dus verkoopprijs wel richting 20 à 30 euro. Wel beetje duur dus.
