Industrial and Systems Engineering Questions

<p>I'm currently a sophomore business major at usc who's about to switch into ISE. Before i commit, I have some questions:</p>

<p>1) What exactly do ise majors study and what type of work do they typically do in real life?</p>

<p>2) how difficult is it to go back and get a business-related job (like financial manager, financial anaylist, etc) with an ug ise degree?</p>

<p>2) How good is USC's Viterbi school of engineering compared to other engineering schools? and their ug program?</p>

<p>Any help in this matter would be appreciated, as i'm trying to gather as much info as i can before making this decision.</p>
