The case for interpretive structural modelling as a technique for enhancing electronic meeting system support

The author describes the use of PRISM, a GSS (group support systems) tool based on the principles of ISM (interpretive structural modeling), using four representative case studies. Each case illustrates the pitfalls associated with generating ideas through simple brainstorming and nominal group techniques, typical of prevailing GSS tools. The strengths associated with ISM are discussed, revealing the potential benefits it offers to the development of more robust GSS tools. The case studies presented show how ISM can overcome the weaknesses inherent in less-structured problem-solving methods, such as Kepner-Tregoe, Porter´s strategic business planning methodology, and Cooper´s new product method, all of which make assumptions about the problem that is to be solved
