The Effects of Numerical and Logical Group Size on Computer-Mediated Idea Generation

Social and Cognitive Influences in Group Brainstorming: Predicting Production Gains and Losses

“…In fact, some comparisons suggest that solitary oral brainstorming leads to more ideas than electronic brainstorming (cf, Paulus et al, 1995). For group sizes of nine or more, electronic brainstorming groups can outperform similar size groups of solitary brainstormers (Dennis & Valacich, 1993;Valacich et al, 1994;Valacich, Wheeler, Mennecke, & Wachter, 1995). However, there is still some dispute about the reliability of this effect (e.g., Pinsonneault et af., 1999).…”

Using group support systems to discover hidden profiles: an examination of the influence of group size and meeting structures on information sharing and decision quality

“…For example, prior research indicates that group size has an influence on information sharing for groups without GSS support (Stasser et al, 1989) and that it may be important for groups using a GSS (Dennis, 1996, in press;Valacich, Wheeler, Mennecke & Wachter, 1995). Meeting structures have also been suggested as being important in influencing information sharing.…”

Structured modeling group support systems: a product design theory

“…Distributed groups may also require software support for both larger group sizes and increased facilitation support, as opposed to face-to-face groups [45]. Group size can affect group work and how members interact [47]. In groups where members are identified, formal hierarchy, or the existence of a leader, may improve Table 1 Components of an information system design theory (ISDT) [48] Design Product Meta-requirements Describes the class of goals to which the theory applies Meta-design Describes a class of artifacts hypothesized to meet the meta-requirements Kernel theories Theories from natural or social sciences governing design requirements Testable design product hypotheses Used to test whether the meta-design satisfies the meta-requirements Design Process Design method A description of procedure(s) for artifact construction Kernel theories Theories from natural or social sciences governing the design process itself Testable design process hypotheses Used to verify whether the design method results in an artifact which is consistent with the meta-design performance.…”
