About the Author

This site is by R&A/Gerben Wierda and about Enterprise Architecture and about Enterprise Architecture Modelling (mainly with ArchiMate®, the visual enterprise architecture language). It accompanies the books Mastering ArchiMate and Chess and the Art of Enterprise Architecture.  The musings here are a personal opinion and are not connected to any institution, other than that experiences and developments there may end up becoming musings here, though never explicitly referring to the organisation. He writes ‘from the trenches of architecture in real enterprises’, his job is to be an actual day-to-day architect in the complex realities of a large enterprise.


Gerben Wierda was, amongst other things, Lead Architect of the Judiciary in The Netherlands, Lead Architect of APG Asset Management, and is now Team Coordinator Architecture & Design at APG. APG manages (Spring 2015) around €425 billion in pension assets for approximately 5 million participants in various pension schemes.
