They engineer processes and systems that improve quality and productivity. They make significant contributions to their employers by saving money while, at the same time, making the workplace better for fellow workers.
Industrial engineers work in many different kinds of businesses and subject areas.
Whether it's shortening a roller coaster line, streamlining a hospital operating room, scheduling an airline fleet of aircraft, distributing products worldwide, or manufacturing superior automobiles, it's all in a day's work. Industrial engineers work in manufacturing firms and service industries. They also work in such areas as a sales and marketing, finance, information systems, hospitals, airlines, banks, railroads, and social services. I would say there is a family atmosphere in industrial engineering. Students really get to know their professors, and professors are interested in students' lives, not just their course work.
