Don't show image this. 回答1: After a short review I would say that your use cases don't seem to be cut the right way. You are using <<include>> and <<extend>> in order to perform a functional analysis. This is not what use cases are all about. Each use case must show a

问题 My requirements experience has been primarily with user stories, not use cases. I've been recently added to a project as a product owner, and the customer is ~80% done with the use cases. Many of the use cases include what would be over a dozen user stories, and the team is discussing how to implement some of the use cases over multiple phases, or how to partially implement to meet schedule. This wouldn't be a problem with stories, but I'm not sure the best way to approach with use cases. Can

问题 I have a question about uml and extend notation of use-case. How I can extend all use case. For example if I created a connection down use case that extend almost all use case, but I don't want to connect all with the notation on the use case diagram cause is very orrible to see. How can I do? 回答1: First of all : the importance of Use Cases Modeling Use Case Diagrams ( Use Case Modeling ) is SO important step in Software Analysis and Use Case Modeling should be performed by professional

Now, to draw up a use case view reports , Is the following diagram correct? It should be noted that the admin are able to view all the reports and the education expert is able to view his self report. Will this change use case diagram? //////According to the answers,I've drawn a new diagram. 回答1: The first thing I notice is your strange actor notation which

问题 Are the relationships «use» and «include» same in use case diagrams? 回答1: «use» is NOT a standard element of use case diagram. But UML standard allows using foreign diagrams elements. So, you can formally use «use» element that normally belongs to class diagram elements and is a sort of Dependency. Its meaning is: A Usage is a Dependency in which one NamedElement requires another NamedElement (or set of NamedElements) for its full implementation or operation. The Usage does not specify how

问题 I'm trying to depict an use case where several actors within a system can perform the same activity. e.g. Let's say (as an example) I want to make the use case "Update Clients" but several identified actors can do this. Manager Chief Executive Customer Service Representative System Administrator Clerk -Do I need to depict all these actors by their roles ponting to the same use case? Manager ------------------------------> |-----------------| Chief Executive ----------------------> | |

问题 Functional decomposition is not used when applied to use case modeling. This phrase is a copied one from a question paper.What is the meaning of that phrase. This is not equal to the question What is Functional Decomposition? 回答1: Use cases deal with synthesizing functions, not decomposing them. A technician decomposes a system to find the pieces it is built of. A business analyst tries to stack single parts of a system on piles so they are formed around a single goal. A use case describes a

问题 I am working on a use case diagram of a fully automated system. An external system will trigger just one use case of this system. Most of the other use cases are scheduled tasks and invoked by the timer. I have a use case that is invoked by the timer and it includes and extends two other use cases. When I write the use case discriptions, who will be the actor for UC-2 and UC-3. Can a use case exists without an actor? I have seen lot of use case diagrams which has included or extended use

问题 I'm creating a Use Case for a project for school and I'm confused about the precondition field. I can understand preconditions like, "must be logged in" or "needs an account." But what if the software is a local setup? To me, it sounds logical that a precondition is that "the software needs to be installed." But on the other hand, this precondition looks weird because otherwise, you would not have this Use Case in the first place. So my question, in short, is: Can system requirements or
