Systemic Understanding of Coopetitive Behaviour in a Latin American Technological Park

The purpose of this article is to construct a systemic structure to explain the relations subjacent to the coopetitive behaviour observed in a Latin American technological park. The research method is qualitative modelling. The primary research technique is the in-depth interview with park experts. Systemic language organised the speeches. The systemic language uses symbols that represent the elements of a system, such as variables, relations, and feedback loops. Initially, we constructed two essential archetypes that describe how the need for coopetition emerged, triggered by failures in meeting customers´ demands and reduced sales. Then, we built an overall systemic structure relying on the essential archetypes, which explains how the coopetitive strategy emerged in the park. The main conclusion reached by the study is learning and public policies as desirable conditions; failure in meeting customers’ requirements as the trigger; and sustainability, knowledge and resource sharing, mitigation of risks and uncertainties, and increased sales by price reduction, as reinforcing feedback factors. The main contribution of the study is a systemic qualitative model that helps understanding how to implement or manage a coopetitive strategy in a network formed of companies mainly driven by technological factors.

Systems thinking,systems practice,and practical philosophy: A program of research

IfSystems Practice is to serve the cause of socially rational decision making, its understanding of systems approach must open itself up to the communicative dimension of rational practice uncovered by contemporary practical philosophy. This programmatic paper argues that building the bridge between the two traditions of systems thinking and practical philosophy is a key challenge to be faced by the systems community. A three-level framework of rational systems practice is suggested as a point of departure for a program of research.     

Critical considerations in the development of systems thinking and practice

This paper is concerned with the development of ‘Systems Thinking.’ In particular, it considers and critiques ‘traditional Systems Thinking’ within the framework of Critical Systems Thinking. Before embarking on such a venture it is necessary to derive a base context from which to develop argument and analysis. Therefore the outline of this paper is as follows: A contextual setting for Systems Thinking, Theoretical Considerations, Soft Systems Thinking and Methodology, and A Critical Systems Thinking (CST) approach. The account of the development of Systems Thinking is followed by a synopsis of a theoretical framework for Systems Thinking which will allow us to gain an understanding of contemporary views. The paper then goes on to review SSM and CST in order to provide a platform for a critique of traditional forms of Systems Thinking. The final section briefly discusses the applicability of CST to the ‘real-world’ context by outlining some current studies being undertaken by the author.

Decision Support Systems (DSS) development using a model of user inquiry types: Methodological proposals and a case study

A study of the DSS implementation area reveals an increased emphasis on methodologies for DSS development. As the DSS field matures, a larger number of methodological options are becoming available to the DSS developer. Existing methodologies have adopted various methods for performing the important task of DSS requirements analysis and specification. In envisaging a hierarchy of requirements analysis methods, a method for improved requirements analysis is proposed to remedy observed deficiencies within it. This method is based on a view of generic types of inquiries or solicitations made by the DSS user during decision-making. This formalism constitutes the basis of a proposed DSS development methodology that offers several benefits to DSS development. The intended benefits include a sharper and more focused requirements analysis to improve the DSS development process. This paper describes the model and methodology, alongside details of a real-world example of their use in developing a Marketing Decision Support System (MKDSS) for the support of marketing decision-making.

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.

The Pragmatics of Educational Systems Design: A Critical Examination

The author critically examines educational systems design (ESD) through the lens of pragmatism. Examining ESD through a lens of pragmatism draws to the foreground issues related to Banathy's (1991, 1996, 2001) idealized systems design for social and societal systems. The author addresses the complex and dynamic nature of systems design, focusing on the systemic processes in which user-designers are continually challenged to inquire, communicate, and consider choices, and make design decisions concerning the nature of the system being designed. The power of social systems design (SSD) lies in the ability to consider the ideal image of a social and/or societal system, critically and pragmatically in relation to creating a new system that will contribute to the evolutionary betterment of society and a sustainable future for humankind. Following an introduction, the author examines pragmatism. Then the author applies a lens of pragmatism, critically, to examine educational systems design in relation to generating change and creating the ideal educational system. The author then argues the pragmatics of educational systems design, concluding the paper with final reflections on ESD as a process.

The Commercialization of the Nonprofit Sector: A General Systems Theory Perspective

A prominent theme in the modern multidisciplinary nonprofit studies is that commercial activities of nonprofit organizations impair the ability of these organizations to deliver their missions. The present research note argues that this criticism of nonprofit commercialization is based on what von Bertalanffy designated as the ??mechanistic?? view of the nonprofit sector. The research note utilizes von Bertalanffy??s general systems theory to argue that nonprofit organizations are open systems maintaining themselves in an environment in which the supply of critical resources is insecure. Accordingly, commercial activities must be seen as the self-regulatory mechanism that enables, rather than hinders, nonprofit organizations to deliver their missions in hostile environments, as they often are today.
