ArchiMate, the enterprise architecture modelling language, is a standard from The Open Group (TOG). Most people infer from this that ArchiMate is an open standard (I did once) and often assume The …| R&A IT Strategy & Architecture

'Reasoning models' such as GPT4-o3 have become a well known member of the Generative AI family. But look inside and while they add a certain depth, at the same time they add nothing at all. Not 'reasoning' anyway. Just another 'level of indirection' when approximating. Sometimes powerful. Always costly.| R&A IT Strategy & Architecture
GPT-3o has done very well on the ARC-AGI-PUB benchmark. Sam Altman has also claimed OpenAI is confident that it can build Artificial General Intelligence (AGI). But that may be based on confusions around 'learning'. On the difference between narrow, general and (introducing) 'wide' AI.| R&A IT Strategy & Architecture
Google has announced 'Willow', a quantum computer that can calculate so fast it would take a supercomputer 10 septillion (a 10 with 25 zeros) years to do the same. But while the science is real and cool, the message is misleading. An explainer for non-physicists.| R&A IT Strategy & Architecture
[Sticky] Link to the YouTube video of the 'fundamentals' part of my 2024 talks on insights into the digital revolution. About how the IT revolution provides reliable performance, but the price paid is less agility (IT is brittle and thus ever more It becomes ever more difficult to change). About how we humans react/have reacted to this and why 'Complexity Crunch' and not a 'Singularity Point' is coming. Also contains links to related posts on the site for those that rather read than watch..| R&A IT Strategy & Architecture
Mastering ArchiMate 3.2 has been released. Finally. This post contains release information, and a link to the book's page where you can order the free excerpt (with the entire language description as well as a short BPMN primer) or the entire book (both PDF).| R&A IT Strategy & Architecture
You’re on the Titanic. The engineers are shouting: “The bulkheads are too low! The rudder is too small! There aren’t enough life boats!”. The sailors mumble: “It has been cold, there will be many more icebergs than usual and further south”. The owners are pressing the captain: “You should be in New York in six days, we desperately need a record!”. And the captain thinks: “I have execution power. I can break through. I will be successful.” and orders: “Northerly course an...| R&A IT Strategy & Architecture
Fundamental properties of digital IT have set ons on a road not to a Singularity Point, but towards Complexity Crunch. That has consequences for our strategic (IT) choices and landscapes. A ‘long r…| R&A IT Strategy & Architecture

It turns out that AI has created a whole new language. Humans do not speak it, and they may even mistake it for talk about sex. But luckily Generative AI is able to translate it to something humans…| R&A IT Strategy & Architecture

Because of the sheer volume of IT in the world, the behaviour of IT itself is becoming more and more an ‘independent’ factor, and we humans are adapting to it. Digital enterprise, digit…| R&A IT Strategy & Architecture
