This, I think letting individuals/teams figure it out is the best option. Some projects, and even specific times within a project, call for being physically with the team and other times i am more productive being able to just focus on a task at home.

Also I find that my time spent in the office depends on the season. During the Spring and Fall when it is a perfect temperature for being outside i love going into the office and being able to go out for a nice lunch outdoors somewhere with coworkers.
