Ah the open plan office! What a great idea that sounded like! Everyone can communicate so much more easily, it'll allow the cross-pollenation of knowledge, the flow of ideas, the positive energy! It'll be so much more pleasant to work in without all those pesky barriers around.
At a place I worked, when management out sourced some of the manufacturing they put cubicles on half of the factory floor. The cubicle walls were only 4Â½ feet high and the ceiling about 30. But at least they removed the overhead gantry cranes.
