It's about time for the pendulum to swing back. I began my career about the time the vast open office was being replaced by cubicles. As retirement approaches, I'm seeing single-worker cubicles replaced with 4- to 6-person workspaces. Haven't the schools been teaching group-work methods for a couple of decades? And now those students are in positions to redesign the work place. Of course, it's not important that it work, just that it's different.
A comparison comes to mind, where my town has a couple of parallel streets that were converted to one-way about 1980. In 2010, with a new generation of traffic engineers in charge, the two streets have been converted back to 2-way traffic. Ironically, the arguments and goals for the 2010 change are nearly identical to the 1980 change.
I worked in a big office with already high noise level. No carpet, blank walls and noisy devices working in another room.
Someday our boss decided to invite an external consultant who should improve the productivity. The consultant had the "great" idea to rearrange the site so that the noisy devices were located in the same office together with the employees.
The result: the noise level afterwards was even higher. 5% more productivity but 20% more people calling in sick which should have eaten the more productivity by far.
