A multi-modal approach to soft systems methodology

Sammanfattning: The main aim of my research is to explore ways of enriching Soft Systems Methodology by developing intellectual tools that can help designers to conceptualise, create and evaluate different design alternatives. This directs the focus on the methodology’s modelling phase even though some ideas related to analysis also will be presented. In order to realize this objective the study proposes the following supplements. Firstly, a framework of 15 modalities (knowledge areas) is suggested as a supplement to existing analysis techniques, with the aim of helping the analyst identify important aspects that need to be understood in order to identify relevant issues for modelling. Secondly, a concept called qualifying function is proposed as an additional modelling tool for drawing out different perspectives of a particular problem situation, discussing desirable purposes for the design, and for exploring the underlying rationale behind a suggested transformation or a stated Weltanschauung. Thirdly, an expansion of the measures of performance used in SSM modelling, for evaluating conceptual models of possible design alternatives, is suggested. This expansion also builds on the modal framework. Based on both the theoretical and the practical work I have done I conclude that using the modalities as a general framework in analysis, modelling and evaluation, as well as using the concept qualifying function to tease out and clarify relevant transformations and underlying value systems has practical benefits and therefore can be said to enrich Soft Systems Methodology.
