205 p.An increase in group size may result in a decline of group productivity because the factors that undermine group productivity will become more severe as group size increases [Steiner, 1972]. Group Decision Support Systems (GDSS) can help to alleviate the problems that increasing group size can bring to a group (as was found by Gallupe et al. [1992]). The effects of increasing group size may also differ if the task that the group performs changes. Therefore, our objective for undertaking this research is to investigate whether group performance will be affected when groups of different sizes perform different group tasks in the face-to-face GDSS environment. We also aim to find out if group perceptions will change when group size increases.ACCOUNTANC
