Achieving Consensus within SSM
Berg,T , Pooley,R , Queenan,J

Abstract
SSM is a socio-technical system methodology offering tools for analysing complex situations. This modelling approach identifies differing worldviews of the system by encouraging discussion and debate. Academic ethical studies of moral philosophy have been extensively studied but rarely attributed to system modelling. We investigate the possibility of an ethical dimension to SSM comparing it to the ethical theories of duty,
conduct and justice. This paper identifies the key problem areas when requirement gathering in group situations. We investigate the negative groupthink syndromes that occur within groups and discuss the concept of ‘fairness with particular emphasis on the management of facilitator power. It is concluded that participatory system methodologies that feature holism and worldviews have clear links with moral philosophy.. The desirable system outcome requires man and machine to work in harmony. This can be better implemented when there is a deepened understanding of the moral complexities of group requirement gathering.
