It is not clear whether improvements found with group technology are due to the structure embedded in the technology or the added benefit of the technology in managing information complexity. Process complexity is proposed as the explanatory factor in previous coafiicting results. Task complexity is clarified and a Process Complexity Model is proposed and tested. The principal factors manipulated are task complexity (complex and less complex) and technology (present or absent). Ill-structured policy tasks are employed and, in addition to other outcome variables measured, task outcome quality is quantified by comparing the reported results of policy experts ir, these 'asks. Since small group size (three to four) may be the reason that previous experiments have not shown significant differences, group size is controlled using larger groups of seven or more members.
