I don't think that's like DevOps, though. A closer analogy would be a business that only hired EngDocs, doctors who had to be accredited engineers as well as vascular surgeons.

I don't think anyone thinks siloes are themselves a good thing, but they might be a necessary consequence of having specialists. Shift-left is mostly designed to reduce conversations between groups, by having individuals straddle across tasks. It's actually kind of anti-collaboration, or at least pessimistic that collaboration can happen

Oh, I completely agree! We created “EngDocs”, as you say, and simply made the situation worse. An EngDoc is an obviously ludicrous concept, on its face. But by breaking down the silo in the biomedical example, each engineer becomes a bit knowledgeable about an aspect of medicine and each doctor gains some knowledge about aspects of engineering.

I am arguing that all such people, whether developers or ops or ux designers or product managers; need to engage in this learning as they collaborate. This doesn’t mean that we want the DevPM as a resultant title, just that Siloing these different groups will lead to perverse outcomes.

Dev and ops have been traditionally siloed. DevOps was a silly attempt to address it.
