In Phase 1 of this four-phase cycle, requests for new systems or for evaluation of current systems are reviewed. Those seeming to have the most promise in terms of improved instruction, increased efficiency, and economy will be assigned priorities subject to constraints of material and manpower resources. In Phase 2, a detailed definition of the system to be developed will be prepared for projects approved by the review committee. A senior instructional systems analyst will work closely with an individual or committee from the academic department in which the course is taught to develop this description, which will provide a complete specification of the system. In Phase 3, the proposal and project description will be given to a development team consisting of design and media specialists working with a subject matter specialist to design, produce and implement the instructional system. In Phase 4, during the first semester of actual use, the system will be empirically validated by an evaluation team working with the course instructor. Results of this evaluation will be used to revise or redesign the system subject to approval by the department and the review committee. (MBM)
