How do I sign up to start taking courses toward the Graduate in Systems Engineering (GSE) Program or the SE Certificate Program, the IDE SE program, or to just accomplish SE Continuing Education? ? What are the key Commercial Standards for Systems Engineering? What is the difference between an OSS&E Plan and a SEP? ? What is the difference between ANSI/GEIA EIA-632, IEEE std 1220-1998 and ISO/IEC 15288:2002? Why are there other SENG courses listed in AFIT Engineering & Management Catalogue that are not on your web site? Why does your web site not list all of the SE Courses available for Continuing Education?
