Soft System Dynamics Methodology (SSDM): Combining Soft Systems Methodology (SSM) and System Dynamics (SD)

Soft System Dynamics Methodology (SSDM), a systemic methodology product of the combination of two widely used systems-based methodologies from two different systems thinking paradigms, Systems Dynamics (SD) and Soft Systems Methodology (SSM), is presented. The paper argues that by combining some of SD and SSM stages, within the intellectual framework proposed by SSDM, a methodology developed by one of the authors¹ much can be gained in a systemic intervention to tackle complex social problematic situations. A framework for comparing the ontological, epistemological and methodological principles of SD, SSM and SSDM is proposed and the synthesizing and dialectical role of SSDM is advanced. The 10 stages of SSDM are outlined and illustrated by an application on a small Peruvian company; and a set of conclusions and points for further research are discussed.     

从系统方法论看多准则决策的软化

系统方法论与决策范式之间存在对应关系。从系统方法论看,多准则决策属于硬系统方法论,但回顾其发展历程,却能发现其软化的趋势,它已具备了软系统方法论的某些哲学理念和特点,但又与软系统方法论有本质的不同。面对人类活动系统的管理复杂性,硬系统方法论与软系统方法论具有互补性,从多准则决策走向复杂决策,需要软系统方法论的补充。     

Developing an Information System for Sustainable Natural Resource Management in Alborz Watershed, Northern Iran

This article explores the potentials of systems analysis and design of information system for sustainable natural resource management. Soft and hard system analyses were performed to better understand the information needs and design of an information system for improving decision making for achieving sustainable natural resource management. In order to analyze the complex and soft systems situations for developing an effective information system, which meets related actors’ changing needs, a conceptual model inspired by soft systems methodology (SSM) was developed. This model is based on information derived from twelve farmers who were purposely selected to represent diverse conditions and 23 agricultural extension experts across the Alborz Watershed in Mazandaran Province, located in northern Iran. Since a conceptual model resulting from SSM is not in itself sufficient as the basis for the implementation of information systems, a hard system methodology was used to structure the data handling by using unified modeling language. This research has shown the promising potentiality of using soft system analysis methodology as a preliminary step to the actual design of an information system in the natural resource management situation in the watershed system level when combined with hard system analysis methods.     

Application of SSM in tackling problematical situations from academicians’ viewpoints

In recent years, a wide variety of studies have applied soft systems methodology (SSM) to address the complexities of the messy situations. This paper seeks to identify 1) application areas and 2) application levels of the use of SSM in dealing with problematical situations. To do so, 149 articles published between 2000 and 2015 were studied. The findings revealed the application of SSM in new application areas such as sustainable development, knowledge management and project management. The results of this study also indicated that researchers applied SSM at three levels: SSM as a process of inquiry, SSM as an action-oriented methodology, and the hybrid use of SSM. Based on the findings, SSM at the level of a single methodology for bringing out changes has been less welcomed by researchers, but the application levels of inquiry processes and hybrid approaches have been more utilized. This suggests that in the correspondence of SSM with the nature or situation of problems, a sort of incommensurability is witnessed. Factors arising from the nature of the problem, inadequate mastery of the researcher over SSM or the limitations of SSM can exert an influence on this incommensurability.     

The critical kernel in modern systems thinking

This paper unpeels two influential contributions to modern systems thinking, Beer's viable system model (VSM) and Checkland's soft systems methodology (SSM), and finds inside a critical kernel. It is argued, indeed, that these approaches become coherent only when liberated from their regulative shells and interpreted from the critical position. So much does the critical kernel lie at the very heart of modern systems thinking.     

Soft Systems Methodology and Systems Maintenance

Business systems maintenance represents a large proportion of the work of IT staff in most organizations. Many methodologies relevant to IT concentrate on systems development and give little attention to systems maintenance. In this paper we discuss the relevance and benefits of the Soft Systems Methodology (SSM) to systems maintenance. Payroll administration is then used to provide an outline illustration of the use of SSM for systems maintenance projects. Aspects of the use of SSM for systems maintenance projects are also discussed.     

An Idea Ahead of Its Time: The History and Development of Soft Systems Methodology

This paper, part of the Festschrift for Peter Checkland, provides an outline of the history and development of soft systems methodology. It includes a personal reflection on my experiences of SSM, as well as a more objective evaluation of its achievements and limitations.     

Qualifying Function in SSM Modeling—A Case Study

In a previous paper the author introduced a concept called qualifying function as a conceptual tool for modeling and design. The concept was incorporated into the modeling phase of soft systems methodology (SSM), with the purpose of addressing some of the criticism directed toward the methodology, such as its tendency to result in regulatory, rather than radical, agendas for change. It was argued that the concept had the potential to help people in a particular problem situation to view the situation from new and different perspectives and that it could enrich the conceptual models by giving the transformation process a direction. The aim of this paper is to apply the concept, embedded in SSM, to a case study involving two projects, focused on creating new work opportunities, to explore the practical applicability and usefulness of the concept, both in general and as a part of the modeling phase of SSM.     

Bridging Worlds: Information Systems Development Through Cross-Cultural Comparison

This paper reports a case study where soft systems methodology (SSM) was used to help automate a largely manual administrative (examination) information system in a Pakistani university. Various design suggestions for information system improvements, both administrative and IT-supported were made (and implemented) through comparison with another university in Denmark which is well supported by computer systems. An action design research approach with an interpretative epistemology/ontology was adopted. Though the single comparison experience is difficult to generalise, we conclude that SSM (with some adaptations) can enable a socio-technical comparison and design effort and offer a prototype process. The comparison stimulates forward-looking design, but great care must be taken to accommodate cultural differences, and further research is necessary to integrate more sophisticated cultural analysis tools into the design process. The research extends SSM in information system development??from a single situational analysis to a comparative process and can be adapted as a pattern for practitioners with similar automation needs.     

Soft Systems Methodology in Action: The Example of a Private Hospital

The paper dealt with the issues of communication between physicians and patients, health care needs of patients and appointment and documentation systems leading to sub-optimal medical treatment, disorganised files and congestion and improperly stored medical treatment records of patients Two Strands Model of Soft Systems Methodology (SSM) revealed and handled at a private hospital in Turkey. SSM helped make changes as recommendations to the hospital. However, the SSM-based enquiry also disclosed some difficulties in the processes of cooperation between the practitioner and the client, arranging democratic group discussions, drawing rich pictures, designating, listing and selecting organisational concerns, designing human activity systems, comparing conceptual models with the problem situation and offering and adopting changes. Thus, the paper proposed possible solutions to these methodological problems through synthesising relevant key conceptions of specific soft and other change methodologies into a framework that attempted to bring robust developmental specifications and order for using SSM.

Systemic Design for Applying the Combined Use of SSM and CDA to Social Practices

In this paper, we propose a framework for applying the combined use of soft systems methodology (SSM) and critical discourse analysis (CDA) based on social semiotic systemic functional linguistics to social practices. In the social practice, ‘participation’ mode of Checkland’s SSM is used for ‘problem-solving’ whilst CDA is used to problematize ‘problem-solving’ processes within the practice. During the meta-process of problematization of our research, we used Churchman’s systems approach and its theory of ‘boundary critique’ in order to explore issues such as governance, inequality of power, and social values within the organization examined for this study. In other words, the process-oriented methodology proposed in this paper consists of two processes: that of ‘problem-solving’ based on SSM and of problematization of naturalized discourse from the perspective of CDA and two phases of boundary critique in social practice. A detailed account of a case study of Korean social enterprise is given to demonstrate how our proposed framework of the combined use of SSM and CDA is applied into practice. Reflecting the outcome of the case study, this paper argues that critical social research from systemic inquiry using what we call ‘process-oriented methodology’ is useful to address some of the social and complex issues related to understanding dynamic relation between power and discourse amongst participants in the social enterprise in Korean contexts.     

The Use of Soft Systems Methodology to Enhance Group Creativity

Soft Systems Methodology is especially useful in diagnosing and addressing organizational problems and designing new systems in cultures that are characterised by pluralistic views and values. This paper demonstrates how SSM workshops in a large government agency resulted in a high level of creativity. SSM is then proposed as a methodology that could enhance group creativity in organizational design contexts.     

解决不确定问题情境的系统方法论及其反思

解决由人参与的不确定问题情境是当代系统方法论应用研究的主要方向。硬系统方法论采用功能主义整体优化的分析手段来解决目标明确的复杂技术问题,忽视了关于人的价值观和世界观等因素。软系统方法论采用诠释主义的范式来探询和改善问题情境,在处理组织内部关于权力不对等和价值观对立的问题情境时遇到很大挑战。批判系统思想融合了哈贝马斯的三种理性,其中创造性整体论提出了根据不同问题情境采用相适应的系统方法论来解决问题的研究进路。     

System dynamics as a systems-based problem-solving methodology

Systems dynamics is concerned with using systems ideas to increase understanding of various types of phenomena and to aid in the decision-making which determines action upon the processes involved. Developments within system dynamics have occurred mainly independently of advances in the broader systems movement. In this paper an attempt is made to bring to bear on system dynamics some recent work which considers the character of systems-based problem-solving methodologies. System dynamics is placed within a framework which enables the relative strengths and weaknesses of different approaches to be identified. This leads to a deeper understanding of some of the critiques of system dynamics and enables some issues to be outlined which may help to strengthen the theoretical base of system dynamics methodology and hence improve its ability to tackle practical situations.     

Soft Systems Methodology: Other Voices

This issue of Systemic Practice and Action Research, celebrating the work of Peter Checkland, in the particular nature and development of soft systems methodology (SSM), would not have happened unless the work was seen by others as being important. No significant contribution to thinking happens without a secondary literature developing. Not surprisingly, many commentaries have accompanied the ongoing development of SSM. Some of these are insightful, some full of errors, and some include both insight and absurdity. Checkland (1999, p. A42) opines, in the recently published 30-year retrospective, that "SSM has been ill-served by its commentators." Scrutiny of the secondary literature on SSM provides support for this view and also identifies some general characteristics and trends that are important to the development of SSM and, incidentally, reinforces some existing conclusions.     

Suggestions for New Application Areas for Soft Systems Methodology in the Information Age

Soft systems methodology (SSM) is now 40?years old. Another decade has passed since Checkland??s thirty year retrospective on the methodology, published in 2000. It can now be described as an old methodology. But it has adapted and changed over the years and is still very much alive, although the days are long gone when it was mainly developed and practised by its founders at the University of Lancaster. Interestingly, considering that many applications of SSM over the years have been to information systems, it was developed before the age of personal computers and the Internet. The way SSM is viewed has changed over the years as it has been applied to various types of problem situation. Every use of SSM will potentially hold methodological lessons in addition to those about the situation of concern; these may include SSMs framework of ideas, processes and way of use. How is SSM going to change in the future? This will depend in part on the types of problem situation to which it is applied. This paper examines some problem situations associated with emerging technologies in the information age to which SSM has not yet been much applied. These include computer simulation and virtual reality, ubiquitous computing and the design of cities, Information Technology Service Management and the design of enterprise information architectures. Some of the different worldviews associated with these problem situations which could be explored using SSM are noted.     

Total systems intervention: A practical face to critical systems thinking

This is the first exposition of a new methodology (or perhaps meta-methodology) for systems practice known as Total Systems Intervention (TSI). Designed to overcome the weaknesses of hard, cybernetic, and soft systems approaches and build on their strengths, TSI represents a practical face of critical systems thinking. It advocates combining three building blocks-systems metaphors, system of systems methodologies, and individual systems methodologies—in an interactive manner which is deemed to be particularly powerful and fruitful. In this paper the philosophy, principles, and phases of the TSI methodology are set out and two very different examples of its use are provided.
