A participative and facilitative conceptual modelling framework for discrete event simulation studies in healthcare

Existing approaches to conceptual modelling (CM) in discrete-event simulation (DES) do not formally support the participation of a group of stakeholders. Simulation in healthcare can benefit from stakeholder participation as it makes possible to share multiple views and tacit knowledge from different parts of the system. We put forward a framework tailored to healthcare that supports the interaction of simulation modellers with a group of stakeholders to arrive at a common conceptual model. The framework incorporates two facilitated workshops. It consists of a package including: three key stages and sub-stages; activities and guidance; tools and prescribed outputs. The CM framework is tested in a real case study of an obesity system. The benefits of using this framework in healthcare studies and more widely in simulation are discussed. The paper also considers how the framework meets the conceptual modeling requirements

A critical approach to the development of a framework to support the evaluation of information strategies in UK Higher Education Institutions

A thesis submitted for the degree of Doctor of Philosophy to the University of LutonThe objective of this thesis has been to develop a framework to support the evaluation of information strategies of UK higher education institutions (REIs). For this study the theoretical and empirical literature was extensively reviewed and four substantial pieces of empirical research were conducted. These included action research CAR), two pieces of ethnographic research, and a case study. The AR analysed problems encountered with a Student Records System at a UK university and identified both immediate and deeper causes for these problems. Ethnography I involved the researcher's participation in the information strategy development process at the same university: This included consideration of the development processes adopted and also the way that decisions were taken. Ethnography II consisted of participant observation at a range of workshops and conferences organised by the Joint Information Systems Committee on information strategy development at UK REIs. These provided a broad picture of information strategy development procedures being adopted across these HEls. The case study investigated in detail the implementation of an information strategy at a university different from that examined in AR and Ethnography I. These empirical investigations all included in-depth interviews. In total 117 people of various levels and backgrounds involved in information strategies and associated information systems within UK HEIs were interviewed. Key findings from the empirical research were: Many HErs in the process of developing an information strate!:,,),, or about to do so, were not fully sure how this should be achieved nor the extent of the likely benefits. Most HEIs implementing information strategies were using top-down directed system approaches, leaving little room for more inclusive bottom-up emergent planning. Information strategies need to be developed and evaluated using strongly human-centred methods, primarily because it became apparent that the successful functioning of such a strategy is dependent on the motivation and competencies of the people who create and use the information. Investigations into aspects of information strategy development and implementation need to focus on people's perceptions of the situation rather than seeking an objective truth independent of the participants. This reflects a Kantian perspective of knowledge. Overall, the empirical findings supported the use of a Critical Systems Thinking approach in the evaluation of information strategies at higher education institutions. The development of the evaluative framework, the main objective of the thesis, took place in two phases: developing the framework based on the literature review and revising the framework from the empirical research investigations involving a process of critical iteration. The first phase identified a range of elements associated with an HErs information strategy, and for each element highlighted the relevant theoretical andlor empirical literature that bears on the issues being addressed. In particular, the framework is strongly influenced by insights drawn from the work of three key social theorists: Kant, Habermas and Foucault. In addition, the framework includes 'guidelines for evaluation', where these are more practical questions to ask and areas to investigate when evaluating a given element ofthe strategy. The second phase took the framework through a series of reflections and revisions based on the findings from the empirical investigations. In each case, insights were gained that related to the use or applicability ofthe framework. By combining the findings from the theoretical and empirical literature with those from the empirical research, the final framework, which is believed to have filled a gap in the theoretical literature, aims to encompass the complexity of information strategy development and implementation within HEIs. The framework reflects a human-centred and Critical Systems Thinking approach, and is designed to allow potential evaluators to identify underlying causes for the success or failure of an information strategy that is implemented at an HEI

A critical systems thinking approach for the planning of information technology in the information society

This thesis presents a view of the situation of Information and Communications Technology Planning (ICTP) from the perspective of Critical Systems Thinking (CST). Nowadays with the increasing use of information and communications technologies and the possibilities of management of information, organisations and people in general focus attention on the planning of these technologies. Such type of planning has been often understood as a process that aims to get competitive advantage through the use of information and ensure that it will contribute to the improvement of the way of life of societies. The outcomes in different countries and problems encountered make necessary to explore the possibility of an alternative view in planning that could be more inclusive and participative regarding people involved and affected by this process.In this thesis such a view is defined as 'strategic'. It considers that different groups of people have different concerns that are necessary to address. By using a combination between the systems theories of Autopoiesis and boundary critique, the strategic view is presented. It opens the possibility of including different groups of people and their concerns, as well as debating the consequences of addressing some of these concerns in action. Concerns are viewed as system boundaries.A methodological approach to support a process of ICTP is defined from the strategic view. This approach was used to intervene at Javeriana University in Colombia in a project called "Exploring possible roles for information technologies at Javeriana University" from March to July 1999. Reflections about this project lead the author to propose enriching the strategic view with an understanding of the issue of ethics in the practice of ICTP and in the improvement of the way of life of individual and collective subjects. The ideas of power and ethics from Michel Foucault are used to enrich the strategic view of planning and to enhance critique on the ethics fostered by practitioners. This critique fosters also continuous awareness about the life projects of practitioners and of individuals in general, as a proposal to improve their way of life in the development of the information society

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

An assessment of knowledge use and knowledge management maturity among the micro, small and meduim enterprise sector in Zambia

The focus of this study was to establish the knowledge use and Knowledge Management (KM) maturity among the Micro, Small and Medium Enterprise (MSME) Sector in Zambia. This is a domain that has received little attention in the Zambian business and economics literature, partially because of the newness of KM as a business concept. Knowledge Management is a very important aspect as far as innovation and competitiveness are concerned in the knowledge economy. Since the inception of the open market economy in Zambia in 1992 and the move to diversify Zambia's national economy from state control into private hands, the MSMEs still seem to be struggling with lack of innovation and competitiveness. Despite several attempts to boost the sector's viability, little success has been recorded

An Organizational Maturity Model of Software Product Line Engineering

Software product line engineering is an inter-disciplinary concept. It spans the dimensions of business, architecture, process, and the organization. Some of the potential benefits of this approach include cost reduction, improvements in product quality and a decrease in product development time. The increasing popularity of software product line engineering in the software industry necessitates a process maturity evaluation methodology. Accordingly, this paper presents an organizational maturity model of software product line engineering for evaluating the maturity of organizational dimension. The model assumes that organizational theories, behavior, and management play a critical role in the institutionalization of software product line engineering within an organization. Assessment questionnaires and a rating methodology comprise the framework of this model. The objective and design of the questionnaires are to collect information about the software product line engineering process from the dual perspectives of organizational behavior and management. Furthermore, we conducted two case studies and reported the assessment results using the organizational maturity model presented in this paper
