All my life, I've done my programming work either alone at home, in the silence of a library or with a small team in a quiet room. I consider that open offices are a bane to my productivity. I honestly cannot focus without headphones on. However, you have to keep an ear open at all time in order for the benefits of such an office. I often do unpaid overtime simply to have time alone and I consider that during those times my productivity triples. All open office plans should offer quiet private areas for employees where they could go and focus on complicated issues. Sadly, I have yet to see anyone offer it (except maybe the big names like Google and Amazon).
