Industrial engineering is a branch of engineering which deals with the optimization of complex processes, systems or organizations. Industrial engineers work to eliminate waste of time, money, materials, man-hours, machine time, energy and other resources that do not generate value. They figure out how to do things better, engineering processes and systems that improve quality and productivity.

An industrial engineer may visit a hospital or a factory, for instance, in order to improve the site's functionality or efficiency. • They collect data and analyze it with special computer programs. They collaborate with other professionals in their efforts to solve problems. • Traveling is often required, since industrial engineers need to study workplaces and diagnose problems in many different locations. Industrial engineers typically work 40 hours a week.
