Architectural patterns are a key concept in the field of software architecture: they offer well-established solutions to architectural problems, help to document the architectural design decisions, facilitate communication between stakeholders through a common vocabulary, and describe the quality attributes of a software system as forces. Regrettably,(More)
Recent research suggests that architectural knowledge, such as design decisions, is important and should be recorded alongside the architecture description. Different approaches have emerged to support such architectural knowledge (AK) management activities. However, there are different notions of and emphasis on what and how architectural activities should(More)
Web services provide a way to facilitate the business integration over the Internet. Flexibility is an important and desirable property of Web service-based systems due to dynamic business environments. The flexibility can be provided or addressed by incorporating variability into a system. In this study, we investigate how variability can be incorporated(More)
The second workshop on Sharing and Reusing Architectural Knowledge (SHARK) and Architecture rationale and Design intent (ADI) was held jointly with ICSE 2007 in Minneapolis. This report presents the themes of the workshop, summarizes the results of the discussions held, and suggests some topics for future research.
In contrast to software architecture models, architectural decisions are often not explicitly documented, and therefore eventually lost. This contributes to major problems such as high-cost system evolution, stakeholders mis-communication, and limited reusability of core system assets. An approach is outlined that systematically and semi-automatically(More)
In this paper, we introduce a documentation framework for architecture decisions. This framework consists of four viewpoint definitions using the conventions of ISO/IEC/IEEE 42010, the new international standard for the description of system and software architectures. The four viewpoints, a Decision Detail viewpoint, a Decision Relationship viewpoint, a(More)
