Since it was brought up in the Open Concept Floorplan house thread, I'll start it here for offices.
I've seen it good and bad. One of my last Army assignments all the staff and senior leaders had offices. Then there was an open cubicle space for others to work. That was pretty good.
I worked at GSA (General Services Administration) in DC in a building that was constructed in 1919. They've opened that up and do 'hotel' office(ing). So no one has an office except for the Secretary level boss, IG, and General Counsel's office.
Everyone has to schedule a space for daily work and you just bring your laptop with you. So you can end up sitting next to people not even from your section. "Can" because when I was there most sections had sort of laid claim to particular areas and reserved them exclusively.
My take was it really cut down on work flow and product, I believe there was actually a study produced that proved just that. Hard to go speak to someone face to face, which is only amplified now with more remote work.
