Fire prevention initiatives are increasingly being viewed as an effective approach to fire and rescue service improvement. In this paper we examine a research project aimed at investigating the use of a novel multi-paradigm systemic approach to fire prevention support involving the use of interpretivist soft systems approaches combined with experimental scientific statistical modelling. The research project is based upon a 2?year case study in Merseyside Fire and Rescue Service in the UK. The soft systems approach was beneficial for understanding the nature of fire prevention, and the causal factors associated with unintentional dwelling fires. When combined with a statistical modelling approach and a hard systems approach to developing a geographical information system, the result was a useful tool for analysis of unintentional dwelling fires that assisted in targeting fire prevention activities to those most at risk.  相似文献

This paper sidesteps the usual starting points for debate about complexity and the philosophy of science, which tend to assume that science is primarily about observation. Instead, the starting point is intervention, defined as purposeful action by an agent to create change. While some authors suggest that intervention and observation are opposites, it is argued here that observation (as undertaken in science) should be viewed as just one type of intervention. We should therefore welcome scientific techniques of observation into a pluralistic set of intervention methods, alongside methods for exploring values, reflecting on subjective understandings, planning future activities, etc. However, there is a need to explicitly counter a possible pernicious interpretation of this argument: intervention could (erroneously) be viewed as flawlessly preplanned change based on accurate predictions of the consequences of action. This is the mechanistic worldview that systems thinking and complexity science seek to challenge. Therefore, having redefined scientific observation as intervention, the paper revisits insights from systems thinking and complexity to propose a methodology of systemic intervention. Some brief reflections are then provided on the wider social implications of this methodology.  相似文献

A Systemic View of Transformational Leadership   总被引:2,自引:1,他引:1  
A systemic view of transformational leadership is developed. Initially the terms administration, management, and leadership are distinguished. Leadership as an aesthetic function is then discussed. Growth, visions, and strategy continue discussions. It is then argued why leadership cannot be taught. Ways of viewing the world as systems that underpins transformational leadership are then set out. The paper concludes with a discussion of systemic transformation.  相似文献

This paper aims to describe the application of Soft Systems Methodology (SSM) to the reality of a Brazilian enterprise. Systemic practices are ways of putting to use systemic thought in the real world, using the precepts of the systemic approach, which is very important for knowledge management and globalization. The systemic practice SSM is used in the resolution of ill-defined problems, which often involve behavioral variables and, thus, cannot be addressed by the so-called hard methodologies. In this paper, SSM is applied to the problematic of a middle-market business, an auto supply distributor, whose managers consulted the authors of this paper as regards proposing improvements of its performance. As a result of this work, the authors were able to propose core changes in attitudes, leading to changes in structure and process.  相似文献

Managing financial institutions in an underdeveloped economic context has become a real challenge nowadays. In order to reach the organization’s planned goals, they have to deal with structural, behavioral and informational problems. From the systemic point of view, this situation gets even worse when the company does not present organizational boundaries and a cohesive identification for their stakeholders. Thus, European countries have some special financial lines in order to help the development of micro credit in Latin communities in an attempt to help the local economy. However, institutions like Caixa dos Andes in Peru present management problems when dealing with this complexity. Based on this, how can the systemic eye help in the diagnosis of soft problems of a Peruvian financial company? This study aims to diagnose soft problems of a Peruvian financial company based on soft variables like identity, communication and autonomy and also intends to identify possible ways to redesign its basic framework. The (VSM––Viable System Model) method from Beer (1967), applied in this diagnostic study, was used in a practical way as a management tool for organizations’ analysis and planning. By describing the VSM’s five systems, the creation of a systemic vision or a total vision is possible, showing the organization’s complexity from the inside. Some company’s soft problems like double control, inefficient use of physical and human resources, low information flows, slowness, etc. The VSM presented an organizational diagnosis indicating effective solutions that do integrate its five systems.  相似文献

This paper presents a critical analysis of a systemic view of change management and its conceptual underpinnings. It reflects upon the systemic view from perspectives of modernism and postmodernism. The understandings so developed are then synthesised in terms of structuration theory. It is argued that organisational change is characterised by diversity and interactions, which necessitates a systemic approach using multiple methods in one intervention. By making transparent the conceptual underpinnings, it is shown that this systemic view can help build an improved understanding of organisational change characterised by diversity and interactions, and it can support the use of multiple methods to manage organisational change in one intervention.  相似文献

This paper sets out some observations arising from on-going research into the use of systemic methods in the planning of complex projects within the National Health Service (NHS) in Staffordshire and Shropshire in the UK. This brief paper sets out the main reasons for the application of systemic approaches, the nature of the methodologies put in place and some of the outcomes and reflections of those involved in the various workshops. Whilst not attempting to be definitive in our conclusions, the authors believe that the results of the application of systemic methods by Health and Care professionals show a range of strengths going forward.Published with the kind permission of Staffordshire and Shropshire Workforce Development Directorate.  相似文献

This article aims at introducing concepts related to the systems approach applied to the international system. First, the authors describe the systems view considering General Systems Theory in order to conceptualize the international systems as well as the Pluralist Theory of International Relations. Based on General Systems Theory, the authors analyze the international systems from the perspective of the Pluralist Theory of International Relations, using a case study on the European Union. The pluralist image of international systems presents important similarities to Systems Theory, as it analyzes the international context, characterized by variety, complexity and dynamics and uses the concepts of object, attribute, inputs and outputs, environment, motivations and process, which enable a better understanding of the international system.

Quite often over the last decade, heavy equipment manufacturers are trying to improve their project management performance with the use of effective project management methods. However, the challenges encountered aren’t isolated problems and a systemic approach is required. This paper exemplifies how a systemic approach can be applied to heavy equipment manufacturing project (HEMP) management, through of a multifaceted vision. The findings present in the paper are based on a two-year case study in a metallurgic equipment manufacturing enterprise in China. Based on the analysis of HEMP management problems and the contributions on systemic approach application in project management, the paper enriches existing theory by: (1) interpreting the HEMP management system with the top-down disassembly method; (2) developing the collaborative project management approach with a systems view highlighting the project characteristics management and inter-departmental collaboration; (3) making suggestions for systemic approach application in project management. For practitioners and researchers, the findings are particularly meaningful for manufacturing project management and systemic approach application.  相似文献

The Need for a Systemic Approach to Change Management—A Case Study   总被引:3,自引:3,他引:0  
Change is now a constant feature of organizational life, but the effectiveness of change management initiatives is often open to question. By reflecting on a case of change management involving a Higher Education Institution (HEI), this paper argues that, to be more effective, organizational change must be managed systemically. The paper first provides a systemic conceptual underpinning to change management, and then examines the case by comparing what had really happened with what might have happened if organizational change had been managed systemically. The analysis helps build an improved understanding of change management, and provides implications for future change management practice.  相似文献
