An operations specialist is the brain behind the machine who coordinates the workflow over all the departments of a company. They optimize, prioritize, and analyze to make sure nothing takes more time, money, or energy than necessary. They see to it that processes that depend on one another are completed in a timely manner, that every equipment is functional and all necessary materials are on stock, that there is no empty time or overload of work in any department, and everyone is doing what they are supposed to.
Much like the conductor of an orchestra, really. With perhaps less impressive gestures. Although, who knows. They come in all shapes and sizes.
On average, they make $53,767 a year, which seems fair, considering they do have a lot on their plate.
