As a business manager I always wonder if productivity would be higher if I forced my people to come in everyday. When we do get together, I think it turns into a never ending meeting of brain storming always putting us 2 projects ahead in focus. Mostly that maybe a leadership and focus issue? It is true allowing working from home keeps office space costs low and gives talented people the ability to work in their ideal space, but this all is easy to judge if you have a productivity scale.
