Yes, it's a leadership failure and probably time to go, it only gets worse. In my experience. It's a vicious cycle where, as velocity slows, inexperienced leadership gets more and more panicked and starts frantically rearranging projects, features and people in desperate attempts to fix the problem, obviously exacerbating the communication breakdown and gridlock further. It also builds resentment and can turn pretty toxic as everyone starts just looking out for themselves.
