Abstract

a b s t r a c tRecent 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 be supported. This is reflected in the design and implementation of existing AK tools. To understand the current status of software architecture knowledge engineering and future research trends, this paper compares five architectural knowledge management tools and the support they provide in the architecture life-cycle. The comparison is based on an evaluation framework defined by a set of 10 criteria. The results of the comparison provide insights into the current focus of architectural knowledge management support, their advantages, deficiencies, and conformance to the current architectural description standard. Based on the outcome of this comparison a research agenda is proposed for future work on AK tools.

Abstract. Different organizations or organizational units are likely to store and maintain different types of information about their software architectures. This inhibits effective management of architectural knowledge. We experimented with a model of architectural knowledge to characterize the use of architectural knowledge in four different organizations. Based on this experimentation we identified four perspectives on architectural knowledge management, and additionally adjusted the model to better align theory with practice. The refined model defines a minimal set of concepts with supposedly complete coverage of the architectural knowledge domain. Because of the minimalistic aspect of the model, we refer to it as a 'core model' of architectural knowledge. Supporting evidence for the validity of our model, i.e. the supposed complete coverage, has been obtained by an attempt to falsify this claim through a comparison with selected literature. Application of the core model to characterize the use of architectural knowledge indicates possible areas of improvement for architectural knowledge management in the four organizations.
