Use IDEF0 to develop an external system diagram for an information system to advise undergraduate systems engineering students on the development of their plans of study. The information system is the software and hardware system that the undergraduate systems engineering students will use. Assume 193the systems engineering faculty will maintain the accuracy of the courses and prerequisites. Assume the information system can obtain schedule information over a network from the registrar's office. Assume that the information system produces a written plan of study for each student.
