“…The objective of these systems are to improve the effectiveness of the group process and reduce negative effects of groups, including the pressure to conform, free riding of members, and domination of the group by one or more members (Nunamaker et al, 1991). Many GSS will share common characteristics (Finlay & Marples, 1992), including enhanced communication facilities between group participants, enhanced modelling and interface facilities to permit voting and ranking, and the availability of both qualitative and quantitative decision support tools, with which members are comfortable, which are transparent in operation, and which are flexible. Such systems may be designed to embrace features of group-based processes, including processes of information sharing, storage and retrieval, and also of learning (Wilson et al, 2007).…”
