What an interesting and strange article. The author barely offers a definition of “systems thinking”, only names one person to represent it, and then claims to refute the whole discipline based on a single incorrect prediction and the fact that government is bad at software projects. It’s not clear what positive suggestions this article offers except to always disregard regulation and build your own thing from scratch, which is … certainly consistent with the Works In Progress imprint.

The way I learned “systems thinking” explicitly includes the perspectives this article offers to refute it - a system model is useful but only a model, it is better used to understand an existing system than to design a new one, assume the system will react to resist intervention. I’ve found this definition of systems thinking extremely useful as a way to look reductively at a complex system - e.g. we keep investing in quality but having more outages anyway, maybe something is optimizing for the wrong goal - and intervene to shift behaviour without tearing down the whole thing, something this article dismisses as impossible.

The author and I would agree on Gall’s Law. But the author’s conclusion to “start with a simple system that works” commits the same hubris that the article, and Gall, warn against - how do you know the “simple” system you design will work, or will be simple? You can’t know either of those things just by being clever. You have to see the system working in reality, and you have to see if the simplicity you imagined actually corresponds to how it works in reality. Gall’s Law isn’t saying “if you start simple it will work”, it’s saying “if it doesn’t work then adding complexity won’t fix it”.

This article reads a bit like the author has encountered resistance from people in the past from people who cited “systems thinking” as the reason for their resistance, and so the author wants to discredit that term. Maybe the term means different things to different people, or it’s been used in bad faith. But what the article attacks isn’t systems thinking as I know it, more like high modernism. The author and systems thinking might get along quite well if they ever actually met.
