What I find quite interesting that none of the so-called agile frameworks takes the production step into account. Or in other words: how do you expect to be agile if the code you are working with is a chaotic bowl of mess, often called Spaghetti Code, but more accuratly described as Barb Wire Code — as we do get trapped in it.

I have developed an architecture to adress those concerns. https://vikingosegundo.gitlab.io/posts/agile-development-and-architecture/
