On Viable Service Systems: Developing a Modeling Framework for Analysis of Viability in Service Systems

This paper explores the contribution of systems modeling to the design and analysis of viability in service systems. We apply a modeling framework called SEAM (Systemic Enterprise Architecture Method) to gain an understanding of how a service system maintains its identity and remains viable in its environment. SEAM embodies theoretical insights from systems science and organizational cybernetics, in particular the viable system model of Stafford Beer. We illustrate the applicability of the framework by modeling the design of viability in a service system

The complexities of teachers' commitment to environmental education - a mixed methods approach

This article argues that a mixed methods approach is useful in understanding the complexity that underlies teachers' commitment to environmental education. Using sequential and concurrent procedures, the authors demonstrate how different methodological approaches highlighted different aspects of teacher commitment. The quantitative survey examined significant factors that determine teachers' commitment, whereas the qualitative approach used a soft systems methodology to expand understanding and to explore ways of increasing teacher commitment to environmental education. Results indicate a complex range of factors affecting commitment, and different layers of reality discovered by the different methods provide a holistic understanding of teacher commitment to environmental education. The article also demonstrates how a mixed methods approach can serve the dual role of confirming and elaborating findings
