The topic of “abstract” vs “concrete” architecture seems increasingly popular, especially in relation to the ArchiMate language. Recently this topic came up in consulting assignments, teaching settings, and the linkedIn group for ArchiMate. In a previous posting I briefly touched upon this topic when I wrote about the combining the specialization relation and the aggregation relation to create a plug-and-play process architecture. In this posting I will re-examine this topic. The proposed solution has been tried and tested and is now used in several organizations.
