Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

A framework for the analysis and evaluation of enterprise models

Bibliography: leaves 264-288.The purpose of this study is the development and validation of a comprehensive framework for the analysis and evaluation of enterprise models. The study starts with an extensive literature review of modelling concepts and an overview of the various reference disciplines concerned with enterprise modelling. This overview is more extensive than usual in order to accommodate readers from different backgrounds. The proposed framework is based on the distinction between the syntactic, semantic and pragmatic model aspects and populated with evaluation criteria drawn from an extensive literature survey. In order to operationalize and empirically validate the framework, an exhaustive survey of enterprise models was conducted. From this survey, an XML database of more than twenty relatively large, publicly available enterprise models was constructed. A strong emphasis was placed on the interdisciplinary nature of this database and models were drawn from ontology research, linguistics, analysis patterns as well as the traditional fields of data modelling, data warehousing and enterprise systems. The resultant database forms the test bed for the detailed framework-based analysis and its public availability should constitute a useful contribution to the modelling research community. The bulk of the research is dedicated to implementing and validating specific analysis techniques to quantify the various model evaluation criteria of the framework. The aim for each of the analysis techniques is that it can, where possible, be automated and generalised to other modelling domains. The syntactic measures and analysis techniques originate largely from the disciplines of systems engineering, graph theory and computer science. Various metrics to measure model hierarchy, architecture and complexity are tested and discussed. It is found that many are not particularly useful or valid for enterprise models. Hence some new measures are proposed to assist with model visualization and an original "model signature" consisting of three key metrics is proposed.Perhaps the most significant contribution ofthe research lies in the development and validation of a significant number of semantic analysis techniques, drawing heavily on current developments in lexicography, linguistics and ontology research. Some novel and interesting techniques are proposed to measure, inter alia, domain coverage, model genericity, quality of documentation, perspicuity and model similarity. Especially model similarity is explored in depth by means of various similarity and clustering algorithms as well as ways to visualize the similarity between models. Finally, a number of pragmatic analyses techniques are applied to the models. These include face validity, degree of use, authority of model author, availability, cost, flexibility, adaptability, model currency, maturity and degree of support. This analysis relies mostly on the searching for and ranking of certain specific information details, often involving a degree of subjective interpretation, although more specific quantitative procedures are suggested for some of the criteria. To aid future researchers, a separate chapter lists some promising analysis techniques that were investigated but found to be problematic from methodological perspective. More interestingly, this chapter also presents a very strong conceptual case on how the proposed framework and the analysis techniques associated vrith its various criteria can be applied to many other information systems research areas. The case is presented on the grounds of the underlying isomorphism between the various research areas and illustrated by suggesting the application of the framework to evaluate web sites, algorithms, software applications, programming languages, system development methodologies and user interfaces

Automated software systems generation for process-oriented organizations

Tese de doutoramento do Programa Doutoral em Tecnologias e Sistemas de InformaçãoCada vez mais, as organizações suportam as suas operações em sistemas de software. Torna-se, portanto, muito relevante o correto mapeamento das operações nos sistemas de software. Esta tese foca-se em organizações orientadas a processos de negócio, devido à relevância dada pelas normas de qualidade, pelos modelos de excelência, e pelos requisitos dos clientes, a esse tipo de estruturação interna das organizações. Nas organizações orientadas a processos de negócio existem diversos fatores, como o tempo envolvido nos projetos de implementação de processos de negócio em software, as diferenças existentes entre os modelos de processos de negócio e a sua implementação real, ou a quantidade e o tipo de recursos envolvidos nesses projetos, que fazem com que os projetos de desenvolvimento de software sejam demasiado dispendiosos, demorem demasiado tempo, e não garantam que o produto de software resultante seja o mais adequado à realidade da organização que o vai usar. Esta tese propõe que os sistemas de informação e de software devam ser desenvolvidos, desde o início, incorporando os modelos das organizações onde irão ser usados. Além disso, e como existem disponíveis modelos de referência de processos de negócio, esta tese também propõe o seu uso explícito aquando da recolha de requisitos. Assim, o objetivo principal da tese é propor uma metodologia que se inicie com modelos de processos de negócio e que termine com a geração de sistemas de software, para organizações orientadas a processos de negócio. A metodologia denomina-se BIM e é formalizada através do metamodelo EPF. Dada a abrangência dos temas a tratar, a tese foi conduzida tendo em atenção que o processo de desenvolvimento de software para suportar organizações orientadas a processos pode ser otimizado. Para melhor mostrar os diversos passos e resultados intermédios, usamos a metodologia de investigação Action Research. A tese propõe que as atividades de investigação sejam terminadas quando uma dada condição de paragem seja atingida, e para isso usa uma avaliação baseada num conjunto de indicadores para os resultados do produto e do processo, e uma adaptação do modelo de excelência EFQM para a forma como foi executado o processo de desenvolvimento. O foco das Action são os sistemas de software MES, essenciais na ligação entre sistemas de software embebido e sistemas ERP. Nesta tese, as Action iniciam-se com modelos de processos e com arquiteturas de software standard, e terminam com uma proposta de modelo de processo e com arquiteturas de software e tecnologias adaptadas à execução de processos de negócio. A tese propõe também alguns conceitos como IAvO (extensão de modelos de processos de negócio), OBO (componentes de software intermutáveis e não-proprietários), OA (aspetos organizacionais), e PF (framework de processos) para aumentarem a eficiência e eficácia na implementação em software de processos de negócio.Increasingly, organizations support their operations by using software systems, turning very relevant the proper mapping of operations into software systems. This thesis focuses on organizations oriented to business processes, due to the importance that quality norms, excellence models, and customer requirements put on this type of internal structures of organizations. Process-oriented organizations have characteristics, such as the time needed to implement business processes in software, the differences between the business process models and the real business processes, or the quantity and type of the required resources, that lead to development projects too expensive, taking too long to complete, and that do not assure that the resulting product is the most adequate to the reality of the client organization. This thesis proposes that the development of information and software system embodies, since the early stages, the models of the organization where they operate. In addition, and since business process reference models are available, the thesis also proposes to use explicitly such reference models by requirements collection time. Thus, the main goal of the thesis is to propose a methodology that picks business process reference models and ends with software systems, for process-oriented organizations. The methodology is denominated BIM and is formalized by using the EPF metamodel. Due to the wide scope of the studied areas, the thesis is tailored considering that the development process for processoriented organizations can be optimized. To express better the intermediate steps and results, we use the Action Research methodology. The thesis proposes that the research activities terminate when a stopping condition is met, based on a set of indicators for the product, and a tailoring of the EFQM model for the development process. The Actions are focused on MES, crucial for the linking of embedded software systems with ERP systems. In this thesis, the Actions start by using standard process models and software architectures, and end by using a proposed process model, and software architectures and technologies adapted to the execution of business software. The thesis also proposes new concepts like IAvO (extension to business process reference models), OBO (interchangeable and nonproprietary software components), AO (organizational aspects), and PF (process framework) to increase the efficiency and the effectiveness of the implementation of business processes in software

An evaluation of the challenges of Multilingualism in Data Warehouse development

In this paper we discuss Business Intelligence and define what is meant by support for Multilingualism in a Business Intelligence reporting context. We identify support for Multilingualism as a challenging issue which has implications for data warehouse design and reporting performance. Data warehouses are a core component of most Business Intelligence systems and the star schema is the approach most widely used to develop data warehouses and dimensional Data Marts. We discuss the way in which Multilingualism can be supported in the Star Schema and identify that current approaches have serious limitations which include data redundancy and data manipulation, performance and maintenance issues. We propose a new approach to enable the optimal application of multilingualism in Business Intelligence. The proposed approach was found to produce satisfactory results when used in a proof-of-concept environment. Future work will include testing the approach in an enterprise environmen
