The use case ends You need to define the flow of the use case if you are designing the software or the process. In our example, the preconditions are that: In our example, there are several ways that exceptions can occur: Just look at our use case diagram example which is based on the example we have been using: By knowing all the exceptions, you will be easily able to define what needs to be done in such a case.
That click is what starts the use case within the support system. The Sales Department — If the customer is unable to get their problem fixed they might want to return the product, which will be a loss for the sales department. In UML terms, we say that the first use case includes the second.

Exceptions This dictates what happens when a failure occurs in the flow. Flow You need to define the flow of the process that starts when a use case is started.
They are then shown an error message. You then take the other scenarios and write them as extensions. Any good system needs to have precautions in place in the case of failure. Basic Flow The basic flow is the best case scenario of what should happen in the use case if all the conditions are met.
References Example Use Case Description To write the content of a use case, you begin by picking one of the scenarios as the main scenario. The level depends on the type of a company; a normal electronics company will classify most consumer complaints as high level while general feedback will be classified as being on a lower level.
