User Interface Design and Use Case Realization

Question 1 – User Interface Design – 30 marks

Given a full use case description, design a user interface to support that use case. Illustrate your design with a set of annotated storyboards, and explain your design choices with reference to user interface design principles

Part 1 - Storyboards  - 20 marks 

Given a use case description and a System Sequence Diagram showing the information flow requirements for that use case, develop a set of dialogues/storyboards that support the information requirements for that use case.

Part 2 - UI Design Principles - 10 marks 

Discuss/explain your UI design with reference to principles of UI design, and architectural requirements.

Question 2 – Use Case Realization – 70 marks

Given the full use case description and a domain model perform a Use Case Realization to support at least the normal flow through the user interface you just designed. Illustrate your realization with a sequence diagram and a design class diagram.
Note: the use case realization is to be performed within a single execution context. Represent all remote parts of the system (if required) as actors.
Also Note: The use case realization is to be performed using the ‘perfect memory assumption’ – no data access operations are necessary.
Final Note: the purpose of use case realization is to produce a set of design classes which can be directly implemented as software in code.

Part 1 - Sequence Diagrams (50 marks)

Using a boundary class for each node of your UI design, assigning a use case controller class, and using the domain model provided, describe the collaboration between classes necessary to support the information needs of the use case. Illustrate at least the normal flow. Those intending to achieve higher grades should also illustrate first major alternate flows and then minor exception flows. 

Part 2 - Design Class Diagram (20 marks)

Apply the results of your use case realization to create a design class diagram showing class attributes and methods required to support the illustrated flows of the use case.
