the right hand doesn't know what the left hand is doing

One part of an organization or group does not know what the others are doing. I thought I was supposed to order shirts for the family reunion, but now I hear Aunt Jean did that already.

We both scheduled meetings in the conference room at the same time because the right hand doesn't know what the left hand is doing.
