This is the 3rd posting in our series on ArchiMate. So far we have discussed the history of ArchiMate and the rationale behind the framework (three layers: business / application / technology, three aspects: active structure, behavior, passive structure). In this post we zoom in on the core concepts from these three layers. That is, we’ll present the “core concepts of ArchiMate’s core”. In the second part of this posting we’ll also dive into some more advanced concepts. It should be noted that this posting is not intended as a full-blown course. Formal training his highly recommended (See the site of our academy for our training offering) and all the details of the language can be found in the ArchiMate 2.0 specification at the website of the Open Group.
