  • You have to submit your answers in a Word file.

  1. As a usability expert, you are hired by a health system to improve their health software primarily used by physicians and nurses. You may have to do a complete overhaul of the existing user interface.  You also learn that the health system has purchased the Microsoft Health Common User Interface (CUI) that offers many of the tools and widgets that you can use to build the GUI (a widget list shown below).

Based on what you have learned in this course, can you explain the process that you expect to follow to undertake this project? Remember that you are a usability expert and manager, and you will have programmers that will work for you.

 Your answer will be judged based on the thoroughness of the procedural detail and usage of the techniques you learned within the process.
