Process thinking has expanded in recent years mainly due to the need for improved quality of operations. As a result of this, there is a growing need for business modelling and analysis techniques that provide justification for understanding and analysis of the organisational environment with the aim of developing appropriate solutions for redesign. There is a lack of systematic approach that can lead a process redesigner through a series of steps for the achievement of process redesign. Most of the existing methodologies are based either on real life experience with little attention on the modelling and analysis of the business environment or vice versa. In this paper we present a manufacturing company case study describing a specific framework for business modelling and analysis.

Abstract Business process redesign (BPR) has its roots in the manufacturing industries. In manufacturing, the emphasis is usually on the description of the flow of material through manufacturing processes. More recently, BPR has been taken into consideration by the management accounting and information systems development community. Each one of these communities has focused on different aspects of BPR, with its own weaknesses and strengths. Lately, BPR methodologies based on organisational theory have started ...

This paper presents the application of a Fuzzy Cognitive Map (FCM) based theoretical framework and its associated modeling and simulation tool to Strategy Maps (SMs). Existing limitations of SMs are presented in a literature survey. The need for scenario based SMs with inherited ability to change scenarios dynamically as well as the missing element of time are highlighted and discussed upon. FCMs are presented as an alternative to overcome these shortfalls with the introduction of fuzziness in their weights and the robust calculation mechanism. An FCM tool is presented that allows simulation of SMs as well as interconnection of nodes (performance measures) in different SMs which enable the creation of SM hierarchies. An augmented FCM calculation mechanism that allows this type of interlinking is also presented. The resulting methodology and tool are applied to two Banks and the results of these case studies are presented.

Petrochemical plants have inherent economic and personal risks associated with their operation. To give a concrete illustration of the scale of loss of life, personal injury and costs which can arise from plant incidents, the New York Times of 19th June 1991 lists 14 petrochemical disasters from 1987 to 1991 in the USA alone. Figures for these incidents were 7 dead, 138 injured and a cost of 5246 million. It is therefore in the interests of the plant owner 10 apply best practices 10 ensure safe and cost effective plant operation, and it is in the public interest to encourage this. There are two root causes of incidents leading to personal and economic loss. One is the lack of a trusted means for operational staff 10 access consistent, reliable and high quality information about the plant's overall operational status and the procedures for operating it Secondly, there is the absence within management of a verifiable organisational model that accurately reflects the required behaviour of the organisational agents in performing safety-critical tasks. This is a necessary foundation 10 cope with the 'multifarious changes and unexpected events that occur in a complex plant The LIFETRACK project brings together an international petrochemical company (BP), a supplier of plant information and control systems (Honeywell) and an academic decision-support group. We are working IOgether in a united" attempt to make an in-depth investigation inlO the information needs of plant personnel when operating in safety-critical situations and how reliable information systems can be designed and maintained over the lifetime of a plant This paper illustrates how we have been developing the object-relationship modelling (ORM) and Object Life Cycle (OLC) languages for the problem of designing an organisational model as a prerequisite to an information system 10 support permit management. In addition 10 this, we also demonstrate the application of an object-oriented variant of the Z specification language 10 the verification of this model. Through this example, the principles of organisational modelling and verifICation for safety-critical tasks we are developing for the LIFETRACK project will be illustrated.

During execution, a system records a series of data useful for both scheduling of tasks and for overall performance evaluation of the process and other organisational elements. These real-time data allow the comparison between planed and actual performance. In this paper, we present a process monitoring tool that integrates process modelling and analysis tools with human resource management and management tools. The aim of the tool is to allow performance measurement at both the individualistic (employee) level and the holistic ( ...

Speech and language therapists (SLTs) are faced daily with a diversity of speech and language disabilities, which are associated with a variety of conditions ranging from client groups with overall cognitive deficits to those with more specific difficulties. It is desirable that those working with such a range of problems and with such a demanding workload, plan care efficiently. Therefore, the introduction of methodologies, reference models of work and tools, which significantly improve the effectiveness of therapy, are particularly welcome. This paper describes the first web-based tool for diagnosis, treatment and e-Learning in the field of Language and Speech therapy. The system allows SLTs to find the optimum treatment for each patient, it also allows any non-specialist user--SLT, patient or helper (relative etc.)--to explore their creativity, by designing their own communication aid in an interactive manner, with the use of editors such as: configuration and vocabulary. The system has been tested and piloted by potential users in Greece and the UK.

Scholars and practitioners in the fields of Business Process Management (BPM), performance measurement and business information systems tend to use different approaches for implementing BPM Programs without arguing about the quality strategy set to ensure successful implementation and adoption. This lack of quality standards makes it difficult for researchers and practitioners to build on each other's work. The purpose of this article is to present a model for a BPM Program implementation in the banking sector. The authors' four steps implementation model is based on a quality strategy monitoring the different phases of the entire procedure. Through this work, they aim to identify the key characteristics of a BPM system as well as open a debate on what are the necessary and sufficient conditions for the full implementation of a BPM Program. The authors review the relevant literature and present their BPM implementation approach. Based on their research, they presented a case...

Recent studies have shown that long-term monitoring of asthma severity can reduce asthma exacerbations, optimise drug therapy and decrease the cost of asthma management. The management of a chronic patient is a collective and cooperative enterprise that may exploit Information Technologies (IT) to improve the overall quality of care. The aim of this paper is to present a web based asthma tool that significantly enhances public information and awareness to support illness prevention, patients independent living through user profiling and personalisation and collaborative work between health professionals, therapists, caregivers and patients through Tele-Care and Tele-Consultation. The system has been tested through a preliminary survey that took place in UK and Greece.

PurposeThe purpose of this article is to address the measure selection problem and to propose the use of a multi‐criteria approach to address the problem more effectively. The main objective of this research is to propose a methodology (not a new performance measurement framework) that will support existing measurement framework(s) during the process of performance measurement systems' design, implementation and use, and to advance the decision‐making process.Design/methodology/approachConforming to the most favoured approach, the balanced scorecard is adopted to illustrate the proposed methodology. This paper briefly illustrates the application of the proposed methodology. This illustration is based on a real case study from a Greek financial institution, which has considered the proposed methodology in order to select appropriate measures. The paper begins with a brief literature review on the balanced scorecard, the theory of MCDM and smart technique. In section three the pro...

BPR methodologies should justify their capability for understanding an organization's strategy, business structure and processes. For this reason techniques that provide understanding of the current and future desired positions of the organization and the discrepancy between them as well as consistent business modelling techniques are required. One of the main drawbacks of existing business modelling methodologies is the lack of theoretical underpining associated with the concepts used in business modelling. ...

A plethora of BPR methodologies have appeared in the literature during recent years, however, most of them present serious limitations mainly due to the need for a multi‐disciplinary approach. In this paper we present an overview of existing work in the area of BPR with the aim of highlighting the different categories of BPR methodologies identified in the literature, their focus on the redesign process and the general BPR principles that emerge from them. We also present a BPR methodology called Agent Relationship Morphism Analysis (ARMA) that goes beyond the limitations of the existing BPR methodologies taking a holistic view of the organisation. In ARMA the modelling of the business environment is achieved with the use of three perspectives: the structural, behavioural and process. The use of these three perspectives provides insight to the relationship between organisational structure and organisational processes.

UNESCO has been urging countries for the last decade to undertake initiatives to enhance Technical and Vocational Education and Training (VET) which should be a vital aspect of the educational process in all countries (UNESCO, 2001). This demand has driven countries to embark on their individual "quality missions" in an effort to uncover the best approach to embedding quality management into their reform programs. Quality implementation in VET has been approached differently depending on the countries' culture, their education systems, and their societies rules and values. This paper presents what quality, in general, means and some of the main concepts associated with its implementation and assurance. Additionally, the aim of this research is to gauge the concept of quality management in Vocational Education and Training (VET). Thirdly, this paper looks to disseminate what has been discovered and highlight paths that those concerned with VET are taking.

Abstract: In the existing BPR methodologies there exists a big division in business analysis techniques due to the black and white approach used in most cases. In some of them, cost is the central issue, in others generic management or the successful use of IT. As a result business analysis techniques are directed towards this central issue ignoring any other means of analysis. Agent relationship morphism analysis (ARMA) is a BRP methodology that applies different analysis techniques from various disciplines in different perspectives. ...

Despite the rhetoric surrounding performance-driven change (PDC), articulated mechanisms that support intelligent reasoning on the effect of the re-design activities to the performance of a business model are still emerging. This paper describes an attempt to build and operate such a reasoning mechanism as a decision support supplement to PDC exercises. Fuzzy Cognitive Maps (FCMs) are employed as the underlying performance modeler in order to simulate the operational efficiency of complex and imprecise functional relationships and quantify the impact of process re-engineering activities to the business model. Preliminary experiments indicate that the proposed hierarchical and dynamic network of interconnected FCMs forms a sound support aid for establishing performance quantifications that supplement the strategic planning and business analysis phases of typical PDC projects.

This paper addresses the problem of designing an “intelligent” decision support methodology tool to act as a back end to financial planning. The methodology tool proposes a novel approach to supplementing typical financial strategy formulation projects by utilizing the fuzzy causal characteristics of Fuzzy Cognitive Maps (FCMs) to generate a hierarchical and dynamic network of interconnected profit and loss (P&L) concepts. By using FCMs, the mechanism simulates the efficiency of complex hierarchical financial models with imprecise relationships and external stimuli while quantifying the impact of strategic changes to the overall P&L status. Generic maps that supplement the decision making process demonstrate a roadmap for integrating hierarchical FCMs into the P&L model of typical financial sector enterprises. Preliminary experiments indicate that ex ante reasoning of the impact of strategic changes (actual or hypothetical) to the status of financial performance can be effective and realistic, without employing detailed P&L numerical calculations.

Fund management is a major function for most financial sector enterprises with geographically dispersed activities. The risk associated to such managerial decisions affects directly the continuity, profitability and reputation of the enterprise. This paper presents a knowledge modeling methodology tool to act as a decision support mechanism for geographically dispersed financial enterprises. The underlying research addresses the problem of financial information capture and representation by utilizing the soft computing characteristics of Fuzzy Cognitive Maps (FCMs). By using FCMs, the proposed mechanism generates a hierarchical and dynamic network of interconnected financial knowledge concepts, simulates the operational efficiency of distributed organizational models with imprecise relationships and quantifies the impact of geographically dispersed activities to the overall business performance. Generic adaptive maps offer an alternative approach to financial management based on strategic level knowledge modeling and integrate hierarchical FCMs into the decision making model of typical financial sector enterprises. Finally, this paper discusses experiments with the proposed mechanism and comments on its usability.
