In the context of this paper, task complexity refers to the degree of complication involved in the decision making process and is described in terms of those factors that define the nature of the problem being solved and the degree of difficulty involved in reaching a solution. In this paper, type of task will be viewed from the standpoint of its impact on task complexity which in turn influences the relationship between semiotic process quality and GSS quality. For example a problem involving strategic planning normally incorporates a greater degree of complexity than an operational control problem. Degree of uncertainty refers to the degree of indeterminateness involved in the problem solving process. It may relate to the uncertainty about the consequences of the decision or to the information provided to make the decision or both.
Time horizon adds further complication to a problem.
R2 - Semiotic process quality is positively related to task complexity. As task complexity increases semiotic process quality must also increase in order to maintain GSS quality. R3 - Semiotic process quality is negatively related to group cohesiveness. As group cohesiveness decreases semiotic process quality must also increase in order to maintain GSS quality. These three hypotheses have important implications for the development of group support systems.
