This assignment continues work on the online booking facility introduced in assignment $11,$Discovering Requirements,$$ and continued in assignment $12,$Design$,$ Prototyping and Construction.$$ Using any of the prototypes that you have developed to represent the basic structure of your product, follow these instructions to evaluate it:

Based on your knowledge of the requirements for this application, develop a standard task $($for instance, 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 and the contents of the form.

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

Note the problems that each participant encounters. If possible, time how long they take to complete the task. $($If you happen to have a camera or a smartphone with a camera, you could film each participant.$)$

Since the application is not actually implemented, you cannot study it in typical settings of use. However, imagine that you are planning a controlled usability study and an in$-$the$-$wild study in a natural setting. 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 this prototype in$-$the$-$wild?
