In this whitepaper we introduce an approach to use ArchiMate for Enterprise Architecture modelling in large teams. The usage of viewpoints makes it possible to reduce complexity in modelling. Generic functions in EA and specific more advanced functionalities in Add-ons makes it possible to support an architecture modelling team in creating validated and quality models of the enterprise. Configuring enterprise architect and the Add-ons for organisation specific viewpoints can be complex and requires knowledge on both the ArchiMate modelling techniques and configuring the functionalities and add-ons. EAxpertise has created multiple example repositories for specific ArchiMate viewpoints. In these repositories the functionalities and add-ons are configured in an extensive manner. When you want to introduce this approach in your organisation please contact us. We can help you making a jump start with the introduction of ArchiMate viewpoints and a repository configured in an effective manner to support your ArchiMate modelling team.
