Decision development in small groups: III. A multiple sequence model of group decision development.

This paper argues that traditional models of group decision making as a series of discrete, consecutive phases are inadequate. It advocates replacing them by a more complex and accurate model of continuously‐developing threads of group activity. In section I the phasic model is evaluated in view of recent research on decision development in small groups. To overcome several problems with the phasic model section II develops a new model, which conceptualizes decision development as a set of continuously evolving tracks of activity, intertwining over time. Based on previous research, this model advances a new descriptive system, which specifies (a) three tracks of group activity, (b) several types of “breakpoints” which mark changes in the development of the strands, and (c) a structural model of task accomplishment. The interrelations among the three descriptive components give a more complex and accurate picture of decision development than the phasic model. In section III, two explanatory factors which d...
