In an earlier job, we moved from a cubicle office to an open office. The open office was supposedly there to facilitate group work. But we were soon told that since everyone could hear and see what we were doing, we were no longer supposed to meet and talk with colleagues at our desks as we had been doing (too distracting for others).
What happens in our open office which is half engineering is that nobody says much of anything. It doesn't help collaberation. If we had cubes or god forbid OFFICES with CLOSABLE DOORS we could have 1-1 conversations whenever we like.
