That’s interesting but I’d have to wonder how effective it is for traditionally more introverted teams like engineering. Do they enforce a certain amount of time someone must be in their “office” and thus primed to be interrupted, maybe even only doing lite work? Or is this a case that works really well for only largely extroverted teams, sales, product, marketing etc.

My suspicion is a non trivial amount of introverted staff will just never have an “open door” so to speak, but then you miss out on valuable interactions for the broader organization or team even if locally for the person they’re uncomfortable or annoying.
