The development and use of a computer-based career system at Georgia State University to provide occupational and educational information to current and potential university constituents is discussed. The delivery areas and activities of the Georgia Career Information System (GCIS) are analyzed through the reduction model, a general systems model developed for evaluating program attrition patterns. This analysis creates a matrix of questions directed toward identifying information and services. The questions can be grouped into four basic categories: type of decision (e.g., continuation, withdrawal); type of individual; circumstances surrounding the decision; and system response. Specifically, decision feedback questions (i.e., the issue matrix) help to identify the existing or potential paths of individuals through education, occupation, and social service components. The reduction model uses the three basic systems of elementary, secondary, and postsecondary education. The combination of the reduction model and the issue matrix provides a method for rational assessment and planning. (SW)
