I agree with everyone opinion, but communication is an important key for the relationship between the departments because if one of the departments finds a problem, they need to alert the rest of the departments. A company does not run with one department, it runs with multiple departments because the all have a purpose which intertwines. Communication between the departments will help reduce mistakes because they will be prepared. I agree with hzy2 opinion regarding the departments understanding each other roles because it helps them work better together, understanding what they do can create a bridge between them.
