Questions

  1. If user attitudes are personal and subjective, why does Jordan say it's possible to get quantitative (as opposed to qualitative) data about user attitudes?

  2. Why is participant time an important consideration in planning a usability evaluation?

  3. Suppose you need participants for an evaluation of a totally new type of software product -- say the Spanish/English translation software we discussed with an earlier chapter. Where would you find representative users, and how would you convince them to participate?

  4. Consider the case study described in this Chapter. Suppose the goal was to perform a "competitive analysis" to determine if this particular product is any better or worse than competing products.

  5. Consider the case study again, from a different angle. Suppose that you got conflicting information from the questionnaire (where users said their expectation is to be able to complete a particular type of analysis within 20 minutes) and the experiments you ran on the "improved" interface (it always took more than half an hour to complete the analysis). What would you recommend, and how would you justify that recommendation?

  6. On p. 103, Jordan says that the main source of information on user attitudes toward the product would be the questionnaire. Where else (which other evaluations) would user attitudes become clear? Would they be likely to be the same attitudes, or different, and why?
