Research on improving the cognitive effectiveness of conceptual modeling languages visual notations often lacks empirical consideration of the people and modeling tasks involved. Such consideration can generate insight into cognitive requirements set by different modeling tasks. In this position paper we propose an empirical research design for gaining a deeper understanding of the difference between...
IT has changed business model and business process, and has become an essential ingredient for the competitive advantage. Under such circumstances, a conventional requirements engineering methodology is not sufficient. We propose an IT-driven business model design methodology in order to take advantage of innovative information technologies. The proposed methodology includes XBMC (eXtended BMC), an...
Legal regulations play an important role in the design of information systems and their related organizational systems. A legal assessment subsequent to the system's development can demand expensive modifications or even the need for replacing existing systems. Legal infringements and resulting disputes can permanently damage an organizations image. To avoid these problems, we argue for the consideration...
Information systems are complex and because society heavily depends on them, they have to be developed using the right enterprise architecture frameworks (EAFs). Although some major EAFs have been developed for more than a decade, information systems still fail to satisfy demands that organizations face and this reduces their competitive abilities. The failure may be due to the fact that either the...
This paper presents the system Avalore, which was design for supporting the selection of research and development projects (R&D). The evaluation model embedded in the system is briefly presented, the decisions about the used technology and system architecture are described, and the essential characteristics of the system are referred.
All the major methods of modeling design in use each have their own characteristics, but none of them can fully satisfied the requirement of architecture data modeling design. To settle this problem, the ideology of visual modeling is introduced to bring into play the advantages of structural analysis method, object-oriented analysis method and model driving architecture method that are applied at...
Little effort has been put into understanding how trust can be modelled and reasoned when developing information systems. Equally little effort has been put into developing visual languages to support trust modelling. Our motivation comes from this situation and we aim to develop a visualization language for trust related requirements elicitation. In this paper we highlight the lack of substantial...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
