Translation of "Departments" in Chinese

Those two departments are sometimes at odds with each other.

那两个部门有时候意见相左。

Instead of just the marketing department completing all their work objectives is not as effective as all the departments working together and mutually realising all the objectives.

与其仅仅营销部成功地完成自己的工作目标，不如所有部门一起合作，共同实现所有目标。
