Here is a good example, of Automattic (makers of WordPress) via Hans de Zwart

"In Automattic’s company creed it says: “I will communicate as much as possible, because it’s the oxygen of a distributed company.”.

They would say that their productivity as a company is dependent on how well they communicate. There is also the aspect of personal productivity: there are many examples of how liberating it can be to be able to really make your own schedule and be flexible. It can also be challenging to get to focus sometimes. In their employee-edited employee fieldbook they have collated a set of advice on how find focus for your work. The best way to help people focus is to have them work on something that is challenging and meaningful."
