In the previous two posts in this series we introduced the core of the ArchiMate languages existing of the three layers and three columns. However, not all questions that enterprise architects typically face are supported by this core. Think for example about questions around security, risk and implementation planning. ArchiMate is an open standard that allows for the use of and even the extension of the language to support specific modeling issues. This can for example pertain to specific properties for an industry e.g. the financial sector, or support for a specific type of analysis that an organization uses.
This posting will elaborate on the two extensions were added to the ArchiMate specification in the latest 2.0 version: the motivation extension, and the implementation and migration extension. We will start this post by discussing these two extensions.
