Feature Oriented Design Analysis (FODA) diagrams present the design of feature-oriented software applications. In some cases, however, the actual implementation of such an application does not correspond to the design that was set forward by the FODA diagram. Such discrepancies are referred to as the gap between design and implementation. We present a bottom-up approach for generating FODA diag...

For the specification and development of large, distributed, and object-oriented systems, it is often advocated that individual components should be developed in an aspectwise manner, where separate descriptions depict various roles or viewpoints of the objects considered. The introduction of such partial specifications requires extra care when reasoning about systems as several specifications ...

An Interorganizational Business Process (IOBP) is an organized group of joined activities carried out by two or more organizations to achieve a common business objective. A consequence of this is that business process modelling and design used inside an organization have to be enhanced and extended to cope with interorganizational business particularities. Thus, methods are required to describe...

This paper discusses an approach for top-down composition of software architectures. First, an architecture is derived that addresses functional requirements only. This architecture contains a number of variability points which are next filled in to address quality concerns. The quality requirements and associated architectural solution fragments are captured in a so-called Feature-Solution (FS...

In this age of complex business landscapes, many enterprises turn to SOA for aligning their IT portfolio with their business. Because of the enormous business risk involved with replacing an enterprise’s IT landscape, a stepwise migration to SOA is required. As a first step, they need to understand and assess the current structure of their legacy systems. Based on existing reverse engineering t...

The principal aim of the GOLD project (Grid-based Information Models to Support the Rapid Innovation of New High Value-Added Chemicals) is to carry out research into enabling technology to support the formation, operation and termination of Virtual Organisations (VOs). This technology has been implemented in the form of a set of middleware components, which address issues such as trust, securit...

Service Oriented Enterprises (SOEs) outsource their functionalities via third party web services. Therefore, there is a need for a systematic approach to manage the cooperation of the services. SOEs perform their functionalities in an extremely dynamic environment. Changes that happen to a SOE are categorized in two types: top-down changes and bottom-up changes. This paper considers top-down ch...
