Constructing Use Case Diagrams
The following checklist shows the steps necessary for the construction of use case diagrams. After this, we will explain the individual steps further.

Checklist 3.1 Constructing Use Case Diagrams from the External View

Collect information sources—How am I supposed to know that?
Identify potential actors—Which partners and customers use the goods and services of the business system?
Identify potential business use cases—Which goods and services can actors draw upon?
Connect business use cases—Who can make use of what goods and services of the business system?
Describe actors—Who or what do the actors represent?
Search for more business use cases—What else needs to be done?
Edit business use cases—What actually has to be included in a business use case?
Document business use cases—What happens in a business use case?
Model relationships between business use cases—What activities are conducted repeatedly?
Verify the view—Is everything correct?
We deliberately chose the order in which the steps are performed. However, this order is not mandatory, since in practice, the individual steps often overlap heavily.

On one hand, a general understanding of the business system and business processes is important for the realization of each individual step. On the other hand, for many steps it is also necessary to consult knowledge carriers. It makes little sense to cling to the personal view of the analyst, who knows too little about the area of application.
