There's an endless debate about what office configuration is best. After working with hundreds of teams over the past decade as a coach, I have the answer:
There isn't a best configuration.
The debate should be about how we can improve effectiveness as a team. We need to communicate quickly, across disciplines and also get into the flow of our work.
Think of a team having a nervous system. To much noise can be like a convulsion. To little communication can be like paralysis.
Experiment. Explore. Regularly decide as a team how you can improve your effectiveness by tweaking your space.
