Symptom: Misunderstandings or contention within teams often affect team performance.
Problems within teams may arise if mutual accountabilities are unclear.
Ideally, every project team should be led by a "prime contractor" who subcontracts to others in the organization for clearly defined deliverables. This resolves questions of authority.
Furthermore, agreements (contracts) among team members should be made at the beginning of each project, to avoid misunderstandings and delivery problems during the project. And if everyone on the team only agrees to what they can deliver, there should be no disappointments.
