Re: How to Safely Think in Systems
#2> Effective systems thinking comes from the tension between model and reality, without a healthy balance you’ll always lose the plot.
I’ve also heard this as “don’t confuse the map for the territory.”

#5At its core systems thinking is an antidote to reductionism. The essential feature of a system is that it is an indivisible whole and that its features are more than the sum of its parts. Systems lose their properties when taken apart into components, because their properties are the result of interactions between components, not the sum of the properties of components in isolation.
That insight produces the most important practical application of systems thinking, which is that systems always need to be designed from the ground up. People should never try to improve individual metrics, but only improve parts if it improves the whole. That's also what most of the examples in Maedow's book are about that's quoted in the piece.
It's also quite funny to bring up a transition to microservices in the piece in this context. I think microservice architectures are almost always the result of ignoring systems thinking lessons. People start to think in terms of the performance of each individual service, start to develop each service on its own terms, and start to ignore the fact that what matters is the interaction between services. It's exactly the kind of silo-ing that systems approaches try to avoid.

#7None of that has really anything to do with systems thinking. That models change, omit information and don't represent reality as such is true for any kind of thinking, systems or otherwise. That's just a truism. At its core systems thinking is an antidote to reductionism. The essential feature of a system is that it is an indivisible whole and that its features are more than the sum of its parts. Systems lose their…

You might also want to look into real-life studies of efficiency and safety by people such as Deming, Weinberg, Womack, Leveson, Dekker, Shewhart, Hollnagel, Ward, etc. There plenty of evidence that it works, even if Meadow's more popular book isn't filled with references.

#9The article is explicitly framed as some advice, based in experience, on avoiding common pitfalls with using explicit models in systems thinking. As such I think it is a nice read. It is also full of links to other interesting work by the author, not least of which is a tool to assist in system modeling (https://github.com/lethain/systems), and links to other similar tools I was unfamiliar with (https://insightmaker.com), which will make for some fine weekend reading and tinkering.

As I recall, there are problems with the book, because the author actually passed away before it was finished.
The biggest problem IMO is that it doesn't adequately address modeling error. It barely mentions it at all. It simply introduces models that were simulated on a computer, and talks about their consequences. And I remember there being a tenuous connection to the original research, which is notable because I believe the author's group did a lot of it.
So I would be interested in some other high level / overview books on the same subject. I'm not sure I got a lot out of this book. I think the main thesis was to focus on "points of leverage" when trying to change systems. I think it is valuable to hammer that point home, but it's hardly novel, and it wasn't justified with practice. I felt like it was too focused on simulations, and confused the simulations with reality.
