Four categories of challenges have been identified in validating the multifaceted fully online cross-national CSCW environments set up in our project iCamp: Organizational constraints for recruiting facilitators and students; Pedagogical defining cultural boundaries, translating self-directed learning concepts into practice, and tracking social networking; Technical – interoperability issues an...

Originally, Data Warehouses (DWH) were conceived to be components for the data support of controlling and management. From early on, this brought along the need to cope with extensive data preparation, integration, and distribution requirements. In the growing infrastructures for managerial support (“Business Intelligence”), the DWH turned into a central data hub for decision support. As the bu...

Modeling and simulation technology is the use of models to develop data as a basis for making managerial or technical decisions. It can be a valuable tool for program managers—but it is one that is vastly under-used. This article provides a business-case framework (a methodology to evaluate investment opportunities) for program managers within the Department of Defense to use when determining h...

Requirements traceability is central to the issue of requirements management, which is essential for producing quality software. Our focus on requirements traceability addresses aspects related to software development and evolution. Our survey deals both with technical and managerial aspects and aims at contextualizing requirements traceability as well as providing basic reference on the subjec...

Software development by formal methods involves an overwhelming amount of technical and managerial detail. Systematic organisation of this information in a method's support environment is an important engineering concern. In this paper, we introduce a model for object organisation in software environments for formal methods, with particular emphasis on easy construction, modiication, review and...

This paper presents the application of the sensitivity analysis techniques Design of Experiments (DOE) and metamodelling to the agent-based model AgriPoliS, which is a spatial and dynamic simulation model of regional structural change. DOE and metamodelling provide a more systematic analysis of results of complex simulation models. When summarising the results, it becomes clear that interest ra...

We describe, in this paper, a component-based software engineering method for helping development teams to plan, organize, control, and develop web applications. The method is described in terms of three methodological elements: a product model that captures the architectural characteristics of web applications, a team model that describes the different roles to be played by the members of a te...
