Es taucht ja immer wieder die Frage nach dem “Return On Investment” des Usability Engineering auf.
What is ROI?
ROI (or return on investment) refers to the returned value in profit, savings, or productivity that can be attributed to a given investment. When the investment is lower than the resulting gains, a positive ROI is achieved. For example, if a company spends $10,000 on advertising efforts that result in increasing profits by $50,000, the ROI is $40,000.
