Whatever helps the project succeed you should pursue. Again do not duplicate information unnecessarily. Look for the most elegant way to capture the system and communicate with the project s stakeholders. The use-case diagram references behavior through a set of activities. Use this diagram to make certain that the work remains in scope. The stickmen and circles provide a good scoping mechanism for the project but do not have the ability to show detailed flow. Do not misuse this tool and try to turn it into a flow or business-analysis mechanism. The activity diagram provides a high-level overview of a system not tied to system classifiers. Use this diagram to show the flow of a system even for things going on outside of the system you build. The diagram can provide a useful you are here map for everyone communicating about the project. In addition the diagram can help in the definition of domain entities with the input and output pins that can link to real system elements. Object diagrams and internal structure diagrams can provide some important information about which classes have active behavior. These diagrams provide a required input for the interaction diagrams and state machines. The interaction diagrams can show the detailed messages that occur in a specific action or set of actions. Such detail gets very close to the code level and provides a good way to communicate about the interaction between objects. Use this diagram for review of issues closer to the implementation code. You can link the sequence to an action in your system which lets you move easily from an activity diagram down to a sequence diagram. The state machine shows the complex life cycle of an object. Use this to review active objects or the internal dynamics of the more complicated objects in your system. Some use state machines as the core diagram
