From my experience it's almost cyclic. In any set of tasks there is a phase where there's a lot of direct communication to get the ball roaling, but then there will be a zone where asynchronous communication will be ok as long as a response comes within dozens of minutes. Then at the end of a cycle there will be more discussions about the produced features/goods and it sall starts again. I wish it was easier to move from an open space model to a walled one depending on the needs. After a few years I started hating having headphones all day long, so my solution is to get away from my desk and find odd places where few people go, but it's of course not scalable nor comfortable.
