What is a Use Case Diagram
A use case diagram is an artefact that originates from object-oriented development. It describes the user’s interactions with the system. A use case model is a form of presenting an use case, although not a formal use case diagram per se.
Use Case Modelling
A use case model diagram shows the interactions between the users and the system. Specifically the diagrams that ScopeMaster generates show the interactions between the user and object types. These diagrams are generated dynamically and can be navigated, filtered and reshaped interactively.
ScopeMaster analyses your user stories to determine the functional intent and users. It then generates a use case diagram model which you can explore.
Filter your requirements by clicking on a user. And see the subset of functionality that relates to the just that user. This is a great way to elicit requirements and enrich the conversation with the user and ensure the completeness of the capability.
There is no need to create these diagrams, ScopeMaster does it for you.
From these diagrams you can assess a set of requirements for:
Completeness: visually spot missing functionality associated with a user.
Size: Visually see the functional size of your software.
Complexity: Spot requirements complexity before it impacts your code.
Duplication: Visually spot duplicate functionality between users and objects.
