It’s not precise to say:

“If you cannot deal with monolith, microservices won’t work for you!”.

The actual phrase should be:

"If you can’t deal with modularity, then neither monoliths nor microservices will work for you."

Happy to chat more (SSH Slack?) – we use the Backstage service catalog to locate components and their code and docs including ADRs. High level guidelines otherwise pretty much as above, detailed guidelines evolving (eg what C4 diagrams to use), what’s mandatory, what’s advised

Neutral Quality is too much to ask for, shitty software is the norm. As a testing community, we have failed to make software better. And let me be clear, developers have also failed. We are in the same boat here. I firmly believe that most people working in software de...

We have failed as testers & developers to make software better. It's simply not up to us, and I think we should be honest towards ourselves about how little impact we have on quality.... read the post and make up your own mind.

You can also keep sniffing the copium if that's what you prefer.

We have a dual strategy of transient docs in Confluence and long-lived docs in Markdown displayable in Backstage. Lowest level docs are in the teams’ own git repos so they can change whenever they want. Higher level (system-of-systems docs) are in an enterprise architecture repo as internal o/s

The book or course I think should exist.

"The absolute beginners guide to running your own apps in production"

Starting at building apps that are meant to run in production, through CI/CD, managing data structure changes, producing/consuming/understanding telemetry and incident management.

No amount of automated tests can replace skilled, dedicated testers who know how to do exploratory testing 💪

But consensus isn’t always progress. It often leads to what the Dutch famously call “polderen”—a compromise where no one really gets what they want. The result? Solutions that look fine on paper but lack real buy-in. And without that, implementation stalls, leaving teams frustrated and momentum lost

No disagreements here on those two, but I do wonder if there's a *third* value of software, and that is WHAT WE LEARNED FROM CREATING IT. And, you might not surprised to hear, I think that might even be the *most* valuable thing.

Business architecture = people architecture = technical architecture = business architecture...

Antipattern: org design without consideration of the flow of value or the technical architecture.

Page with the quote in the post, as well as:

Ashby's Law: Address Variety with Variety Of course, our systems exist in complex contexts, with (generally) complex demands.
"In colloquial terms Ashby's Law has come to be understood as a simple proposition: if a system is to be able to deal successfully with the diversity of challenges that its environment produces, then it needs to have a repertoire of responses which is (at least) as nuanced as the problems thrown up by the environment. So a viable system is one that can handle the variability of its environment. Or, as Ashby put it, only variety can absorb variety." - John Naughton
Jabe Bloom: "The quickest way to explain Ashby's Law is as follows: If I am a fencer and I have 3 ways of thrusting at people, and everybody else has three ways of parrying those thrusts, it will be an even game. [.] I will be as in control as I can be. If someone else figures out another thrust, I will then be required to learn another parry otherwise I will always lose." Implication: The more different kinds of customers your business has, the more complexity you will need to absorb, in order to respond to that.

And

Brian Marick: 'In the 80's, Robert Glass analyzed bugs in fielded avionics software. Found faults of omission most important. I liked his characterization of them: "code not complex enough for the problem''

Jabe Bloom: "Sounds like Ashby's Law."
