Abstract

Reference architectures provide major guidelines for the structure of a class of information systems. Because of their fundamental role, reference architectures have to be of high quality. Before accepting a reference architecture, it has to go through a rigorous evaluation process. A number of methods exist for the evaluation of software architectures. In this paper, we analyze the main differences between concrete software architectures and reference architectures. We discuss the effects of these differences on the evaluation of reference architectures and show that existing methods cannot be directly applied for the evaluation of reference architectures. For the evaluation of a reference architecture for e-contracting systems, we used the Architecture Tradeoff Analysis Method with a number of adaptations and extensions. We present our approach and share our experiences from this evaluation process. Based on the analysis and our experiences gained, we present our vision for a method for the evaluation of reference architectures.
