Part 1: Discussion Questions

• Consulting the modified/enhanced UID process we discussed in class, outline the UI evaluation activities that can be performed before system implementation.
• Discuss the similarities and differences between UCD and PD.
• Compare the relative advantages and disadvantages between expert review and usability testing. In addition, compare the usability metrics that can be used for/during these activities.
• What kind of data can be collected from usability testing to measure usability? What about that from expert reviews?

Part 2: UI Design and Evaluation

You may choose to work with the system you selected for hw#1 before, or pick a different system. Now perform the following for this system:

• Design a usability testing strategy to test/ensure the usability of this system
• Define your usability metrics.
• Determine what data to collect and calculate the system usability based on these data. You can make up some sample data to illustrate your approach.
