C773 (USER INTERFACE DESIGN) EXAM STUDY
GUIDE WESTERN GOVERNORS’ UNIVERSITY
Scenario-based design
✔✔An approach to design that seeks to ensure a product's usability by
creating stories about how users will interact with the product
Analysis, design, prototyping and evaluation
✔✔The three phases of scenario-based design
activity, information design, and interaction design
✔✔The three types of scenarios used in the design phase of scenario-
based design
goal, attribute, criteria to measure attainment, targeted users,
preconditions
✔✔Components of a usability specification
Plan and prepare, test, collect data, analyze, draw conclusions, document,
redesign
✔✔The steps of the usability testing procedure
formative testing
✔✔Term for testing done during product design, used to assess the
usability of the in-progress product and the effectiveness of the current
design direction
, summative testing
✔✔Term for testing done after product is finished, used to assess the
usability of the final product and see how well it compares to similar
products
structure principle
✔✔This states that design should organize the user interface into a form
that is clearly understandable for the user
simplicity principle
✔✔This states that design should make common tasks easy to perform
and that it should communicate clearly in the user's native language
visibility principle
✔✔This states that design should make all the necessary tools and
options for a task clearly visible to the user, and should not burden the
user with superfluous information
feedback principle
✔✔This states that design should keep the user informed of errors and
changes of state
tolerance principle
✔✔This states that design should be flexible and forgiving, should
minimize the occurrence of user errors, and reduce the consequence of
the errors via undo/redo
reuse principle
✔✔This states that design should reuse objects and behaviors to
