@grimalkina I remember the very start of devops for having been there, and one (the?) main idea was really "let's get together so we can share the perception of the cost, and pain, and need, and experience them together so that we reflexively understand it".
Sharing experience is the poor man solution to rationalizing "why" and "how", but in a pre-remote work, it worked remarkably, for a very low cost. Oh, and that was before it was hype and when devops was still a team building practice, and not the name of a position.
Having a science about that would be amazing.
