A business analyst (BA) is preparing a requirement package for access management system. A state diagram for entity "User" has been prepared. The BA wants to check the completeness of requirements by comparing different models. Which diagram should be used with a state diagram to verify that all functions are defined to work with entity "User" for the different roles?
To verify that all functions are defined to work with the entity 'User' for different roles, a use case diagram is the most appropriate. Use case diagrams provide a visual representation of the interactions between actors (in this case, different roles) and the system, detailing the various functions and processes that can be executed. This ensures that all functional requirements related to different user roles are captured and defined within the system.
C. Use case diagram
This is a tricky question but the answer is A- Data flow Diagram BABOK V-3 7.1.4 pg. 138 Specify and Model Requirements: Model Requirements • Data and Information: models represent the characteristics and the exchange of information within an enterprise or a solution. Techniques used to represent data and information include Data Dictionary, Data Flow Diagrams, Data Modelling, Glossary, State Modelling, and Interface Analysis. BABOK V-3 10.44.3 pg.349 State Modelling : State Diagram -A state diagram shows the life cycle of one entity, beginning when the entity first comes into existence and moving through all of the different states that the entity may have until it is discarded and no longer of use.
C - Sequence diagrams are used to model the logic of usage scenarios by showing the information passed between OBJECTS in the system through the execution of the scenario ( BABOK v3 10.42.1) A use case diagram visually depicts the *scope of the solution, by showing the ACTORS who interact with the SOLUTION/FUNCTION (BABOK v3 10.47.3.1) *Scope modelling is used to assess completeness [of requirements] (BABOK v3 10.41.4.1)
C. Use case diagram
Saw this on the internet in the course of my research, "State machine diagrams are usually applied to objects but can be applied to any element that has behavior to other entities such as: actors, use cases, methods, subsystems systems and etc. and they are typically used in conjunction with interaction diagrams (usually sequence diagrams)."
Ans C Use Case Diagram Keywords, FUNCTION,USER, ROLES
Answer B. Sequence Diagram is correct.
B is correct. A state diagram for an entity 'User' is created. An entity is an object or concept within a system. A sequence diagram shows how processes or objects interact during a scenario. The link between these two diagrams is 'objects'.
Verify that all functions are defined to work with entity "User" for the different roles? That's typically a use case which represent entity and actors as the roles players
