Spatial Data Infrastructures (SDIs) have been developing in some countries for over 10 years but still suffer from having a relatively small installed base. Most SDIs will soon converge around a service-oriented-architecture (SOA) using IT standards promulgated primarily by the Open Geospatial...

The majority of current information systems were implemented using traditional paradigms which include business modeling techniques applied during the analysis phase such as Data Flow Diagrams and Entity-Relationship Diagrams. These legacy systems are now struggling to cope with recent...

[Abstract]: This chapter examines the potential for Agile methods to provide mechanisms to deal with the software development environment that has evolved in response to the inadequacies of traditional, heavyweight development approaches. A framework is proposed which identifies three major...

Over the last years, significant academic progress has been made in the area of representational analyses that use ontology as a benchmark for evaluations and comparisons of modeling techniques. This paper proposes a research model to guide representational analysis projects, which extends...

Empirical research strategies are undisputedly of paramount importance to rigorous and relevant IS research. Employed practices of empirical research in Information Systems, however, are still considered to be problematic. One related problem in this context is the lack of rigorously developed...

Conceptual modeling is the process of building a representation of selected phenomena in a problem domain for the purpose of understanding and communication among stakeholders (Wand and Weber 2002) in the process of information systems analysis and design. A crucial element in the context of...

Much research has been devoted over the years to investigating and advancing the techniques and tools used by analysts when they model. As opposed to what academics, software providers and their resellers promote as should be happening, the aim of this research was to determine whether...

In this paper, we propose a unified framework for trust management that can cover a broad variety of trust mechanisms including reputations, credentials, local data and environment parameters. The proposed trust management framework leverages established standards and it covers a broad variety...

As process management projects have increased in size due to globalised and company-wide initiatives, a corresponding growth in the size of process modeling projects can be observed. Despite advances in languages, tools and methodologies, several aspects of these projects have been largely...

Organizations invest substantial resources in Enterprise Systems (ES) expecting positive outcomes for the organization and its functions. Implementing an ES is a lengthy and costly undertaking, with general upheaval for many of the organizations. Many organizations therefore are seriously...
