About the Author


I write about Enterprise Architecture, IT and IT Strategy, IT Technology, and the effect of IT on us (persons, organisations, society). This site originally started as a blog about Enterprise Architecture Modelling with the ArchiMate® visual enterprise architecture language, and it accompanies the books Mastering ArchiMate (now in its fourth edition) and Chess and the Art of Enterprise Architecture. Look for the books on Amazon for the reviews. I am very honoured that my EA book lives on Grady Booch’s bookshelf.

More recently I have presented and written about the impact of the Information Revolution on society, e.g. here. Another book might come out of that, but given that I did start to write one on it in 1996 and I never finished it, there might not.

I have worked in real IT for almost 40 years, always at the forefront of actual change. I have been, amongst other things, Head of the Digital Technology department at the Netherlands Forensics Institute, Lead Architect of the Judiciary in The Netherlands, Lead Architect of APG Asset Management, and am currently a Lead Architect at APG. APG manages (Spring 2021) €630 billion in pension assets for approximately 5 million participants in various collective pension schemes. Every time I update a sheet or page with these numbers, I have to up them.I was one of the first postmaster@ in The Netherlands. I was co-founder of the Dutch chapter of the Internet Society. I co-authored a peer-reviewed legal opinion on the effect of IT on the Dutch constitution. I programmed many, many, many lines of code. Many. I run my own stuff (so I don’t become rusty).

I have been writing since I was young. My musings here are a personal opinion and are not connected to any institution, other than that experiences and developments there may end up becoming inspiration for the musings here, though never explicitly referring to or disclosing anything specific to that organisation, unless it is quite innocent. I write ‘from the trenches of architecture in real (complex) enterprises’, as my job is day-to-day enterprise architecture, landscape health, and IT strategy in the complex realities of a large enterprise. I also write based on what my network tells me. And generally, in this location (and others) I like to expose nonsense, waffle, silver bullets, and the like. Those other sites have been/are a.o. Trouw (1990’s), Computerworld NL (1990’s), InfoWorld, Enterprise Architecture Professional Journal, LinkedIn. Above all, the publications — while almost all perfectly serious — are meant to be entertaining for professionals and other interested people. My publications very occasionally lead to speaking and consulting/coaching/training activities, which I also enjoy. The experience with IT in a real job is in the end one of the foundations of all this communicating and I don’t want that well to dry up. Yet.

I hold an M.Sc in Physics from the University of Groningen and an MBA from RSM Erasmus, Rotterdam.

My YouTube channel with a few conference keynotes/presentations can be found here.

You can contact me at info@rna.nl. I am on Mastodon and LinkedIn. I have effectively left Facebook and I will be leaving Twitter.

If you want to stay up to date about my exploits, follow me on LinkedIn (for now). Or just explore this site (as almost everything is published here)
