GOALS

• To examine the use-cases, focusing on the gathering of user interface requirements.

• To create a user interface artifacts section for each use-case.

• To discuss the concept of use-case coupling.

• To create screen structure charts as a preliminary storyboard of the user interface flow.

• To construct the user interface prototype.

• To create screen dialogs to outline perceived interactions and desired outcomes.

• To evaluate the user interface prototype.

• To outline the changes to the use-case and class diagrams on the basis of additional information found during the prototyping effort.
