It seems every tech company has fallen for the open floor plan. I'd love to find a company that respects the desk as a workspace that facilitates concentration and deep-thought. It seems the answer to this problem has become headphones.
How is this acceptable?
Some teams make use of the space better than others, of course, but for my group it's been a huge boon to our collaborative culture. The offices are well-insulated, so you don't need headphones to achieve quiet, but if you want to, you can leave your door open and hear what your teammates are discussing at any time.
Over time we're upgrading our older facilities to the same model, but in general there are few open-plan offices or cube farms in the company, and I highly doubt we're going to build more. Many years ago, our founders made it a company priority to give folks a door they can close, to get away from "it all" and focus.
