Assignment Preparation
You will need to access the link to a classmate's online food
ordering system prototype, as found in the second discussion in
Unit 4, before you begin Part B: Conduct an Expert Review of a
Prototype. You may choose the prototype you would like to
review. Important: If you have not
already uploaded your prototype to the discussion area, do so
right away.
Usability evaluation is about testing your user interface
designs with a representative group of users. Ideally, you need to
learn if users can complete their tasks successfully using the
interface, how long it takes for them to complete the tasks, how
satisfied they are with the application, whether modifications to
the design are needed to improve user performance and satisfaction,
and to see if the application meets usability
objectives. Review the readings and resources related to
usability test plan, as well as the accessibility standards from
Unit 4, and you will be ready to complete the assignment.
Assignment Instructions
Part A: Create a One-Page Test Plan
Create a usability test plan that would—if you performed
it—predict the quality of your users' experience with this online
food ordering system. In Travis's 2013 article, "1-Page Usability
Test Plan," the author describes an agile, one-page test plan
that can help you think through the process of testing your food
ordering user experience design.
Think carefully through the areas described in the plan and
develop a summary of a test plan that will work for the food
ordering system. Use Microsoft Word to write your
summary.
Part B: Conduct an Expert Review of a Prototype
Conduct an expert review of a classmate's prototype,
demonstrating your understanding of best practices for layout and
style. The expert review is one of the many methods of usability
evaluation that you explored in your studies. You will also
demonstrate your knowledge of how human factors should shape
interface design. In this part of your assignment, conduct a
usability test in the form of an expert review of the user
interface design prototype created by one of your classmates, as
described in Nielsen's 1995 article, "10 Usability Heuristics for
User Interface Design." Note: You
are not completing the full test plan you
developed in Part A. This is a different process.
Select a classmate's prototype from among those posted in the
second discussion in Unit 4. This is your own choice.
Review Nielsen's article and concisely explain how well your
classmate's prototype meets each of these heuristics. Please
address each of the 10 heuristics individually; if any of them do
not apply, indicate this in your assignment.
After you have completed the review for your classmate's
prototype, please send the evaluation to your classmate by an
e-mail. Most likely, you will also receive an evaluation. The
usability evaluation you receive will give you an idea of how
a potential user views your user interface design. You will,
of course, still receive feedback from your instructor when you
submit this prototype as part of your assignment.
Part C: Exploring Strategies for Mobile Design
With this final section of the assignment, you will return your
focus to your own prototype.
Refer to the Conducting a Usability Evaluation and
Cross-Platform Design Scoring Guide to ensure that you meet the
grading criteria for this assignment.
When complete, compile all three parts (usability test plan,
expert review, and cross-platform mobile design strategies) in
a single Microsoft Word document and submit it as an
attachment in the assignment area.
