According to me IEs should first try to do something good in technology, then IE proper which human effort engineering, and then as they gain understanding of management issues tackle management issues in their career.
what I mean is a beginning must be made all IEs in technical area which they studied for four years. Then combining the technical with IE is next step. Management and business process issues have to be the third step. While senior IEs in the dept. may tackle management and business process issues freshers have to be put throught technlogy - IE route.
