  1. The benefit of enterprise ontology in identifying business components

    Albani, Antonia; Dietz, Jan L.G.
    Companies are more than ever participating in so-called value networks while being confronted with an increasing need for collaboration with their business partners. In order to better perform in such value networks information systems supporting not only the intra- but also the inter-enterprise business processes are necessary in order to enable and ease collaboration between business partners. Therefore, they need to be interoperable. As the basis for building these information systems the concepts of enterprise ontology and business components are very promising. The notion of enterprise ontology, as presented in this paper, is a powerful revelation of the essence of...

  2. Semiotic engineering

    Souza, Clarisse Sieckenius de
    This paper presents semiotic engineering – a semiotic theory of HCI. The theory has the advantage to integrate back end and front end design and development perspectives into a single metacommunication process that affects the user’s experience and, ultimately, the success of any system. By means of illustrative examples, we show the kinds of effects that can be achieved with the theory, and discuss why a semiotic perspective is relevant for the future of information systems

  3. Reinventing the future: a study of the organizational mind

    Ramos, Isabel; Carvalho, João Álvaro
    This paper describes the concept of the self- and metarepresentation capabilities of the organization, a constituent of what we call the organizational mind. Our claim is that these capabilities are responsible for the emergence of a collective self that is of central importance in the formation of the organizational identity. These capabilities are relevant to the information systems field, as Information Technology applications play a central role in the support of those representational capabilities. The paper presents a summary of a theoretical perspective that supports a research project aimed at developing a framework to guide managers diagnosing identity dysfunctions resulting...

  4. Data modeling dealing with uncertainty in fuzzy logic

    Urrutia Sepúlveda, Angélica; Galindo, José; Jiménez, Leoncio; Piattini Velthuis, Mario
    This paper shows models of data description that incorporate uncertainty like models of data extension EER, IFO among others. These database modeling tools are compared with the pattern FuzzyEER proposed by us, which is an extension of the EER model in order to manage uncertainty with fuzzy logic in fuzzy databases. Finally, a table shows the components of EER tool with the representation of all the revised models.

  5. LUPA: a workflow engine

    Arráiz, Emely; Hernández Novich, Ernesto; Soler, Roger
    Workflow Management Systems depend on a Workflow Enactment Service having several interfaces to establish communication with external applications, manage persistent information and exchange it with similarly capable systems. The study of business processes has shown multiple workflow patterns that have been modelled and implemented in several engines. The Workflow Management Council has combined commercial and academic efforts towards a standard structure for engines and information exchange regarding workflow processes. LUPA is aWorkflow Engine designed around theWorkflow Management Council Reference Model that implements basic workflow patterns with a graphical syntax, establishing their semantics on Interpreted Petri Nets with extensions. It provides a...

  6. Fulfilling the needs of a metadata creator and analyst

    Khusro, Shah; Tjoa, A. Min
    The realization of Semantic Web vision is based on the creation and use of semantic web content which needs software tools both for semantic web developers and end users. Over the past few years, semantic web software tools like ontology editors and triple storage systems have emerged and are growing in maturity with time. While working on a large triple dataset during the course of a research aiming at a life-long “semantic” repository of personal information, besides other semantic web tools, we used several RDF browsing and visualization tools for analyzing our data. This analysis included ensuring the correctness of...

  7. 1.5 million years of information systems

    Christiaanse, Ellen
    This paper develops the argument that information systems have not only existed for the last 50 years (as most accounts of ICT argue) or since the 1700 century (as some more accurate readings would propose), but they are indeed as old as mankind. It provides a historical account of how information and communication systems have greatly interacted with some major transformations in human society, in addition to demonstrating the implications of the most recent changes in the last 10 years with the Internet. It builds on literature which distinguishes 3 major phases in the history of mankind and provides accounts...

  8. Promoting learning practices: moving towards innovation

    Frigerio, Chiara; Rajola, Federico; Santuccio, Alessia
    As many authors have stated, the importance of organizational learning is fundamental in order to gain competitive advantage and survive in a turbulent environment. Many learning models have been studied in recent years. They have been used to analyze practices or aspects of learning in many industries. This paper aims to develop a particular framework in order to understand the determinants for organizational learning, depending on the firm’s general approach towards information and knowledge management. The theoretical framework is derived from Blackler and McDonald’s study, which focused on organizational learning approaches, and from Duncan and Weiss’s work, which studied attitudes...

  9. An analysis of IFIP TC 8 WG 8.6

    Henriksen, Helle Zinner; Kautz, Karlheinz
    The IFIP TC 8 WG 8.6 focuses on the transfer and diffusion of information technology. Since the working group was established in 1993 there have been a number of events where members of the group have produced contributions analyzing transfer and diffusion of IT in different settings and from different perspectives. In this paper we report the result of an analysis of the theoretical perspectives the contributors have applied in the studies. Our analysis suggests that even though there is an even distribution of factor and process oriented studies reported in proceedings the theoretical denominator for the long standing members...

  10. Work distribution, methodology and technology for ISD and maintenance

    Krogstie, John
    The information systems we see around us today are at first sight very different from those that were developed 30 years ago. On the other hand, it seems that we are still struggling with many of the same problems, such as late projects and unfilled customer demands. In this article we present selected data from survey investigations performed by us in 1993, 1998, and 2003 among Norwegian organisations on how they conduct information systems development and maintenance. The investigations looks on many of the same areas as earlier investigations e.g. by Lientz and Swanson in the late 1970’, thus we...

  11. Understanding the future of global software production

    Bharati, Pratyush
    The software industry in India that mostly exports information technology (IT) services has emerged in the last decade as an important constituent of the world software industry. The industry is organized into MNC networks, whose structural, relational, and territorial dimensions has been investigated. The quasi-disintegration and internationalization of MNC production activities, the commodification of services, the availability of highly skilled low cost personnel, and Indian IT services firms link with MNCs have aided in the emergence of IT services industry in India. The research elucidates that MNCs are key drivers in this complex and interdependent network that involve important Indian...

  12. Enterprise applications: taking the open source option seriously

    Navón, Jaime; Riesco, Nicolás
    Free and Open Source Software (FOSS) is becoming more popular. Nevertheless most CIOs wouldn’t even consider this option for their enterprise information technology needs. We found that the three main concerns about FOSS have to do with legal issues, costs and support. We propose an initial framework to look at FOSS in a balanced, unbiased and systematic manner that can be used for evaluation of specific scenarios from very small companies to large ones.

    Karol, Alankar; Williams, Mary-Anne; Elliot, Steve
    This paper contributes to the discipline of Information Systems (IS) by illustrating the continuing evolution of IS applications to a single, core business function. Historical developments in IS and the major global treasury activity, foreign exchange trading, have been examined to establish the context. Findings from a seven year research project into the impact of ICT on financial services and the development of a next generation agentbased treasury management system prototype have been applied. Possible future developments in IS applications are explored in terms of the capabilities of emerging technologies to address current treasury challenges. The implications for practitioners in an...

  15. Business process reengineering role in electronic government

    Martín, Rodrigo L.; Montagna, Jorge Marcelo
    Business Process Reengineering (BPR) came up as a key concept in the 1990s, with a high impact on management and transactions of private companies. However, it has not been so well accepted in public administration. Nowadays, many projects for changes in government are related to electronic government. According to this, this article discusses the role of BPR in this context, its contribution to this kind of initiative, and if it is a required element to go forward. Also, the difficulties in carrying out the BPR in the particular case of e-government are analyzed, taking into account the characteristics of this kind...

  16. Design of the organization of information services in large public organizations

    Wamelen, Johan P. van
    The design of the organization of information services in large public organizations must be improved to give a better answer on the changing political, administrative and social demands being made on large public bodies. At the moment it is not clear how the organization of the information services should function in this respect. Up until now the organization of the organization of the information services is part of the operations organization. The distance to the strategic function in a public organization is therefore large. To make better use of IT it is necessary to bridge these gap. In the last...

  17. Panel: OASIS in the mirror: reflections on the impacts and research of IFIP WG 8.2

    Kendall, Kenneth E.; Kendall, Julie E.; Avison, David; Davis, Gordon B.; Land, Frank; Myers, Michael D.
    What has IFIP contributed to the field of information systems and organizations through the activities of Working Group 8.2, its central working group in information systems? What has WG 8.2 delivered to its constituents? What have the results and impacts of the WG 8.2 been on the larger community? This panel will not shy away from controversy as it discusses the history, contributions, and unrealized potential of research spawned by this working group over the past 30 years.

  18. Data quality management and evolution of information systems

    Batini, Carlo; Pernici, Barbara
    Information systems have been rapidly evolving from monolithic/ transactional to network/service based systems. The issue of data quality is becoming increasingly important, since information in new information systems is ubiquitous, diverse, uncontrolled. In the paper we examine data quality from the point of view of dimensions and methodologies proposed for data quality measurement and improvement. Dimensions and methodologies are examined in their relationship with the different types of data, from structured to unstructured, the evolution of information systems, and the diverse application areas.

  19. Stakeholders selection for interorganizational systems: a systematic approach

    Ballejos, Luciana C.; Montagna, Jorge Marcelo
    Stakeholders identification is a critical task for successful software projects. In general, there are no methodologies that allow performing it in a systematic way. Besides, several facts must be analyzed when the project is carried out in a context formed by multiple organizations. The complexity of these environments makes the task extremely hard. To face these difficulties, stakeholders are defined and analyzed taking into account the characteristics of the interorganizational dimension. Also a methodology is proposed for carrying out their identification that allows systematically specifying all people, groups and organizations whose interests and needs are affected by the information system...

  20. Methodologies for developing information systems: a historical perspective

    Avison, David; Fitzgerald, Guy
    For the past 30 years and more, Information Systems Development (ISD) has been at the heart of the study and practice of Information Systems (IS). This paper examines the history of ISD methodologies and looks at some of the trends and issues concerning ISD, and shows how these have been reflected in methodologies and how organizations use (or do not use) them. Discussion of the present state of the field is followed by a discussion of possible future directions.
