Complete the following questions and activities:

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

(b) 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.

(c) Select three typical users, who can be friends or colleagues (not a group member), and ask them to do the task using your prototype.

(d) Not 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).

(e) Since the system is not actually implemented, you cannot study it in typical setting 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?

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