Your therapy textbooks were certainly not short on jargon. So you probably wouldn’t be surprised to learn that other groups of professionals love to throw around their own insider terms. The business world is especially guilty of this, and one of their favorite abbreviations is ROI.
Like most bits of jargon, ROI is a needlessly technical way to describe a simple concept. It stands for return on investment. Basically, when you spend money (or other resources) on something — hiring a new employee, an updated piece of equipment, a redesigned logo — you hope to get something back, preferably more than you put in.
The amount you get back from any given expenditure, positive or negative, is your return on investment. Smart business people calculate ROI for almost every decision they make.
