2. Description - expands of the name and provides additional information and details regarding the user and the system interaction.

3. Preconditions - criteria that must first be met prior to the execution of the scenario. They can be sucsessful execution of other use cases or assumptions.

4. Scenario - the anticipated series of actions and responses. Depending of the complexity of the use case the scenario maybe is simple as a couple of lines or spend several pages but length should be taken in the consideration. If the scenario is too long maybe it will be better to define other use cases from that use case

5. Results - the final results of the actor system interaction. Reflex the successful compleition of the use case.

6. Alternate paths - variations on the anticipated scenario and represent failiors of the actor system interaction.
