I get where you are coming from, and I certainly do expect actual facts, data, and reasoning to be a part of any serious postmortem analysis. But those will almost always be in relation to a very specific circumstance. I think there is still room for generalized parables such as this article - otherwise, we would be reading a postmortem blog post, which are also common here and usually do contain what you are asking for.
I think you can generalise without resorting to silly games like the article does. I gave some examples in a sibling comment that are high level enough to give an idea of the types of things I’d think about, without locking in to a specific incident I was part of.
