You will need to access the link to a classmates 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. : 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. Create a usability test plan that wouldif you performed itpredict the quality of your users experience with this online food ordering system. In Traviss 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. **please review https://invis.io/DJTTJIM8TS6 (use this link ) Conduct an expert review of a classmates 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 Nielsens 1995 article, 10 Usability Heuristics for User Interface Design. : You are completing the full test plan you developed in Part A. This is a different process. Select a classmates prototype from among those posted in the second discussion in Unit 4. This is your own choice. Review Nielsens article and concisely explain how well your classmates 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 classmates 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. 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. Your assignment should meet the following requirements:
