Starting from this article, I will use a virtual instance to explain how to obtain the use case, and how to determine whether the use case acquisition is complete and whether the granularity is appropriate. In fact, when doing this, we are in the first stage of requirement
After understanding the system goal, the system analyst should first not understand the business details, but discover people and things related to this goal. This kind of person and thing is called stakeholder in English. In Rose, the type of this kind of model is defined as business actor. Some documents are translated into stakeholders, so I prefer the translation method of stakeholders. This introduces
Starting from this article, the author will use a virtual example to illustrate the method of acquiring use cases, and how to determine whether the use case acquisition is complete, the granularity of choice is appropriate. In fact, in doing these things, we are doing the first phase of requirement analysis, the business modeling phase. With this example, I will
