This assignment continues work on the online booking facility introduced in assignment 5-2. Using any of the prototypes you have developed to represent the basic structure of your product, follow the instructions below to evaluate your prototype:

Based on your knowledge of the requirements for this system, develop a standard task (e.g. booking two seats for a particular performance).

Consider the relationship between yourself and your participants. Do you need to use an informed consent form? If so, prepare a suitable informed consent form. Justify your decision.

Select three typical users, who can be friends or colleagues, and ask them to do the task using your prototype.

Note the problems that each user encounters. If you can, time their performance. (If you happen to have a camera or a smartphone with a camera, you could film each participant.)

Since the system is not actually implemented, you cannot study it in typical settings of use. However, imagine that you are planning a controlled usability study or a field study. How would you do it? What kinds of things would you need to take into account? What sort of data would you collect and how would you analyze it?

What are the main benefits and problems with doing a controlled study versus studying the product in a natural setting?
