Mathematical models have been used extensively to describe the judgmental processes and strategies of individual decision makers, but rarely have the procedures been extended to describe the judgmental strategies of decision-making groups. The present study attempts to extend the procedures for the purposes of describing group decision-making…

Studies the sequence of phases in group decision making. Compares the unitary sequence model, which assumes that all groups follow the same sequence of phases, and the multiple sequence model, which assumes that different groups follow different sequences. Results support the latter model and suggest revisions in current decision development. (PD)
