Described are the principles and processes of Instructional Systems Development (ISD). The ISD procedures have been used by the military and industry for a number of years, and this report provides a framework designed for a quick understanding of ISD without the need to locate and research voluminous government publications and other references. ISD consists of five major phases: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Control. The processes represented by this model can be adapted to various instructional programs, and can be used to change and improve ongoing courses and programs as well as to design new systems. An introduction describing ISD, a flow chart model, and separate sections for each phase are found in this report. The document concludes with a selected bibliography, lists of learning categories and guidelines, and a glossary of special terminology. (MP)
