stick figures represent actors in the process, and the actors participation in the system is modeled with a line between the actor and use case. use cases are represented with a labeled oval shape. Notice: we do not need actor X for starting Use Case B due to the "include" stereotype. Pengertian Dan Cara Membuat Use Case Diagram Pada Star Uml Uml is the modeling toolkit that you can use to build your diagrams. Even if you include Use Case B, you need actor Y! Solution: define multiplicity at the association end near actor Y. Now we add an actor Y directly to Use Case B as initiator, and no multiplicities specified (so it is 1.1). That could lead to problems of interpretation when communicating with your stakeholder about an UCD.Īctor X starts Use Case A, but this use case always ("include") Use Case B. If you do not specify multiplicity, UML says it is a mandatory 1 association. design, every binairy association has 2 ends. Usually on does not specify multiplicities of association ends in an Use Case Diagram (UCD). Sure, should be "goal" focust, however it is nice to know about semantics. It is about conceptual modeling with use cases.

It seems that you suffer from FUNCTIONAL DECOMPOSITION in use case analysis which many suffers. A use case can have many scenarious.ĭo not FORGET, use case analysis SHOULD involve WRITING I do not know your "Context".But with over simplification it seems that you have just one valid use case "Make Recommendation".So jusy leave it as so.How user will do "Recommandation" (what-ever it is ) should be in "Make Recommendation" use case scenario TEXT. NotĮxecution order or other shits.Do not forget that you do not design your application while drawing use cases, you specify what kind of benefit/utility it gives the users. While drawing any use case just tell the big GOAL of user. You should explain your use case to your father who has money but does not have a technology expertise.Think of use case as a business case which you want to persuate your father for giving you money to run it as busines.Can you "persuate" your father with this "recommendations level x" use cases? Do not make things more complex for yourself
