Have you noticed how some project teams are efficient, with everyone knowing what to do and contributing fully, while the members of other teams are constantly bickering and don't seem able to get out of each other's way? Often this is an orthogonality issue. When teams are organized with lots of overlap, members are confused about responsibilities. Every change needs a meeting of the entire team, because any one of them might be affected.
