Industrial Engineering challenges you to improve, design, manage, evaluate, and test production systems. You’ll be looking at the how’s of the economy; this means looking at how a product is made or a service is given, and your ultimate goal is to improve the quality of those products and services.
Unlike other engineering majors, Industrial Engineering focuses on people. You’ll have classes in ergonomics and human factors and study how people are a part of a production system, of course investigating how they can do work more efficiently, or how a production system can be designed to better serve them.
Although Industrial Engineers originally only dealt with manufacturing, today they have a wider range of options. Food, banking, health care, and commercial aviation are only a few of the sectors that rely on Industrial Engineers to make them more effectively deliver their wares. The skills of Industrial Engineers better countless aspects of our society.

Preparation

A strong background in advanced math and science courses (calculus, trigonometry, physics, biology, chemistry) will be the best preparation for your college courses. Computer proficiency is also very useful, as well as social sciences, like history and psychology.
