Technically speaking, Krannert’s Industrial Management major might be your best choice.
Industrial Management majors take core courses that mirror the Management major. The difference between the two degrees is in the minor that you’ll take. In Industrial Management, your minor will be technical in nature, either from the Krannert School, the School of Science, or the Schools of Engineering.
If you are interested in business, and enjoyed your math and science classes in high school, you should check out the Industrial Management major.
