A class project in a systems programing course at the University of Michigan sought to produce a system realistic enough to warrant production use, the underlying assumption being that the reality of the project would motivate students and provide them with valuable experience. Eighteen experienced students in the Computerized Registration Involving Student Participation (CRISP) project worked with the Michigan Terminal System to produce an on-line course registration system for students which would interface with those main parts of the current system dealing with room scheduling, transcript production, etc. Interfaces with the current Data Systems Center were ordered, student groups with individual functions were organized, and internal and external specifications stipulated. The student-designed system was sucessfully demonstrated, resulting in support from the cnetral university administration for further development and eventual implementation of the system. The conclusion was therefore reached that a class project could produce a realistic system, 1) provided that good tools are available, particulary a general-purpose time-sharing system, and 2) that continual guidance on the interface with the system's eventual environment is maintained.
