26. THE ETHICS OF USABILITY TESTING
Molich, Rolf, and Jakob Nielsen. How to Conduct Usability Studies. USA: Nielsen Norman Group, n.d. PDF.
27. THE ETHICS OF USABILITY TESTING
• Don’t allow managers to watch usability tests if their staff are the
participants.
• Emphasize that you’re testing the website or application, not the test
participant.
• Make the first task incredibly simple.
• Observe strictly your own rules for handling video tapes.

28. SELECTING GOOD TEST TASKS
AND SCENARIOS

29. SELECTING GOOD TEST TASKS AND SCENARIOS
• Focus your test on core tasks, rather than on what’s new or fun or easy to test
• Let test participants define their own tasks.
• Write scenarios — not just tasks.
• Avoid tasks you think are humorous.
• Avoid hidden clues in task descriptions.
• Give the test participant a goal but avoid describing the steps.

30. RUNNING THE TEST

31. RUNNING THE TEST
• Sit with the test participants.
• Let test participants explore the site for one or two minutes initially.
• Ask the test participants to tell you if there are any graphics that they wouldn’t expect to
be links.
• Be diplomatic when test participants blame themselves.
• Wait a few minutes before you help.
• Help immediately if the participant is struggling with something that you already have
sufficient data about.
• Watch your tongue & your body language.
• Show your appreciation for any participant suggestions.

33. REPORTING TEST RESULTS PROCESS
• Ask your customer about reporting requirements
• Do a quality and usability check of your test report.
• Let the project team comment on the usability report
before you show it to others.
• Setup a database of reports that is easily accessible.

34. REPORTING TEST RESULTS
REPORT FORMAT
Molich, Rolf, and Jakob Nielsen. How to Conduct Usability Studies. USA: Nielsen Norman Group, n.d. PDF.
35. REPORTING TEST RESULTS REPORT FORMAT
• Make it short.
• Consider the following usability test report format
• Executive summary (1 page)
• Test participant profiles (1 page)
• Test results (5–7 pages)
• Appendix: Test script, including test scenarios
• Appendix: Screenshots annotated with key issues.
• Include a one-page executive summary
• Top 3 successes
• Top 3 problems
• Your conclusions and recommendations.
Molich, Rolf, and Jakob Nielsen. How to Conduct Usability Studies. USA: Nielsen Norman Group, n.d. PDF.
36. REPORTING TEST RESULTS REPORT FORMAT
• Classify all comments
• Problems
• Positive findings
• Suggestions from test participants
• Functional bugs
• Usage scenarios, where test participants describe their work.
• Include quantitative data
• The number of people who successfully completed each task.
• The number of people who experienced a particular problem.
• A breakdown of problems by experience level.
Molich, Rolf, and Jakob Nielsen. How to Conduct Usability Studies. USA: Nielsen Norman Group, n.d. PDF.
37. REPORTING TEST RESULTS REPORT FORMAT
• Develop a consistent report format
• Use an attractive and usable professional layout
• Stress that problem descriptions should be considered generic
