A collaboration diagram focuses on the organization of objects that must cooperate, by exchanging messages, to satisfy a certain behavior. A collaboration diagram is goal-oriented and, as a result, must show only those objects that cooperate in achieving a certain behavior. The main value of a collaboration diagram is that it presents a clear picture of what an object expects from another. Therefore, a set of collaboration diagrams for the behavior of the system and its components would contribute greatly to the refinement of class responsibilities.
