What is industrial engineering?

A commercial reminded me a practical definitionWe do not make a lot of products or services you

use, we engineer industries more efficient for better and cheaper products, faster responses, easier and more sustainable operations, etc.

- Definition by IIE

IEs work in a variety of businesses IE education offers the best of both worlds: engineering &

business (product, service, people and organization)Shortening customer waiting in theme parksstreamlining an operating roomdistributing products worldwide…

As companies adopt continuous productivity and quality improvement, the need for industrial engineers is growing

They work to eliminate waste of time, money, materials, energy, and other commodities

Info from College Board

Career Develop efficient system to deliver products or services.

You should Find and solve problems Know statistics, computers, stochastic process and optimization Write reports, give presentations and communicate with others

It Helps to Be... An organizer, a puzzle solver, and someone who loves order IEs need to listen, explain, and teach

Outlook Economists predict IEs will grows faster than other occupations through 2016. More openings because IEs tend to become managers.

Compensation Starting GT IE is $58,000, May 2008 Those graduated between 3 and 6 years are $69,886 The U.S. Bureau of Labor Statistics estimates: average in 2007 as $73,490
