  5. 5. Myths of Usability Testing Need a lab Testing occurs at the end of the dev cycle Must test everything Need to test 100 people A “good” test means no changes Usability is “system testing”, “user-acceptance testing”, etc. Need a large test team, each playing a specific role/part 5
  6. 6. Just Do It! Make it realistic Any location Any stage of development (earlier is better) Start small  Test an idea (not a feature)  Just a few users Anytime (un-moderated) 6
  7. 7. Getting Started 7
  8. 8. Plan and Prepare for the Test • Scope the effort –Budget, resources, goals, time –Put together a test team • Design the test –Goals, participants, tasks, measures, methodology, team roles etc. –Summative or formative? 8

  26. 26. Selecting & Preparing Materials 26
  27. 27. Why Use a Script? Promotes consistency in conducting the test Reminds to welcome and thank people Reminds to reset/configure between participants Ensures NDAs and other legal requirements are not missed Prepare for non-native language speakers  Tell me more… 27
  28. 28. Parts of a Script Welcome to participants Steps in test (forms, tutorials, tasks, questions) Thank you to participants (and incentives if any) Notes to yourself Reset/configuration prompts 28
  29. 29. Test Folders Organize materials per participant Easily access individual results Store as a group Prepare a folder for each participant  All test materials (script, forms, printed tasks etc.)  Don’t use names- label folders: Pilot, P1, P2, P3 29

  31. 31. Interacting With Test Participants 31
  32. 32. Welcome Make sure the participant feels welcomed and appreciated. Stress that you are not testing them, rather you are testing… Encourage feedback, positive or negative  “I was not involved in the design of this so you can’t hurt my feelings” 32
  33. 33. Facilitating Follow your script Frame questions in unbiased manner Remain passive in facial expressions and body language as much as possible while participant is working Don’t lead or give clues (unless frustration is clear and evident) Probe don’t demand Gently prompt during think-aloud protocol if necessary 33
  34. 34. Probes Ask open-ended questions Encourage participant to elaborate Use participant’s words Listen for vocalizations and watch non-verbal gestures Have participant tell you when they are done Give them time to think 34
  35. 35. Example Phrases How does this compare with your expectations? What specifically are you referring to? What are you looking for? Tell me more… Can you give me an example? 35
  36. 36. Common Issues Refusal to critique  Ask preference and to compare interfaces  Watch what they DO, not what they SAY Taking control - diverting to their issue  Let them see you are listening and writing it down If no resolution, thank and end session - give them the incentive. 36
  37. 37. Getting Users Unstuck It’s not a question of “if” but “when”  Users might be embarrassed at what they perceive to be their fault  Users may not be able to articulate what they don’t understand Don’t directly answer initial questions 37
  38. 38. Getting Users Unstuck Progressive assistance  What are you trying to do right now?  What do you think the next step is?  What would you do in this situation if you were at work? Hints  Do you see anything that might help you? (small hint)  Have you checked the Help? (medium hint)  What do you think the xxx button does? (large hint) End before frustrated, or take a break 38

  46. 46. Low- fidelity/Paper Prototypes Includes wireframes Good time to get initial feedback on concept, word choices and placement Participants  May not be able to understand  May not be act the same as online Always test again later in development 46
  47. 47. High Fidelity Prototypes Ideal time for testing – early enough in development, but participants can “kick the tires” May be difficult to test with (broken links, undeveloped material, etc.) 47
  48. 48. Functioning Products Great for redesign projects – prior to start Get baseline and goals for improvements  Reduce task sequence from 10 clicks to 5  Reduce time to perform task from 10 min to less than 3 min  Increase satisfaction from 4 to 5 on a 5-pt scale Use existing data (Analytics, Help Desk, etc.) to create tasks and inform study 48

  53. 53. Ideal Scenario During your search for a local phone book, you notice a hotel chain’s digital Kiosk, and you decide to try it. You need to:  Reserve a Hotel Room for the evening. (A room with 1 bed for 2 people, non-smoking)  Request transportation to the Hotel  Reserve transportation from the hotel back to the airport 53
  54. 54. Alternative Scenario You want to go to the hotel right away to change before going to a fancy restaurant downtown. You need to:  Know if the hotel provides transportation.  Reserve a room with a King-Size bed because you're fat and you want a view of the ocean.  Make sure that your “friend” who is coming tomorrow will have a room available next to yours. 54

  59. 59. Resources 59
  60. 60. Usability by the numbers… 80% of SW life cycle costs occur during maintenance 80% of maintenance costs are due to unmet or unforeseen user requirements Only 20% are bugs or reliability problems Typical software program released with 40 usability design problems Over 70% of CIO's state that one of their biggest problems is communicating with users to understand their needs 60
  61. 61. Number of Participants • Contentious issue • Nielsen - 5-7 participants uncover ~80% of major usability problems • IF representative • IF doing representative tasks. • Testing more = significant diminishing return. • Virzi and Carol Barnum • Small number of users is sufficient. 61http://www.useit.com/alertbox/20000319.html Jakob Nielsen’s Alertbox.

Watch for these types of observations and put additional Questions/Ideas on the back. Content in this document described by Vijay Kumar in his book: 101 Design Methods Physical What do they interact with? Cognitive How associate meanings? How learn? Social Interactions, decision making, scheduling, work? Cultural What are shared norms, habits, values? Emotional What emotions are expressed and how? What are your biggest takeaways? What did you learn? What surprised you? What is the participants need? Interview & Observation Notetaking Form
  72. 72. Observer RulesEveryone who observes a design session is asked to abide by a set of rules.The purpose of these rules is to minimize stress for the participants and to maximize the amount of information we get from the study. Stay for the entire study  Distractions are unhelpful and participants may get the impression that you’re leaving because they’ve done something wrong (e.g. walking out in middle of a movie). If you can attend only part of a study, discuss with the facilitator beforehand to determine whether there is a way to accommodate this. Don’t reveal information about the study to the participant  It is often more useful to explore an area of difficulty in detail rather than try to “get through” all the topics. The facilitator will track time so that we can cover as many of the important areas as possible. Respect participants and the confidentiality of their data  We have promised the participants that their participation is confidential.This means that we should not include their names in any reports or other communication such as email, and we should refrain from discussing them by name outside the test setting.  Do not make negative comments about people—there is always a risk that a derogatory comment could be overheard or otherwise make its way back to the user. Adapted from the book Paper Prototyping by Carolyn Snyder, published by Morgan Kaufmann Publishers. Copyright (c) 2003 Elsevier. All rights reserved.
  73. 73. Observer Rules (continued) Remain silent and silence phones  You may notice something so surprising that you are tempted to laugh or exclaim out loud.This is not unusual. Unfortunately, participants might think you are laughing at them. Keep as quiet as possible. You will have opportunities to ask questions at the end. If necessary, pass a note to the facilitator.  Observe only - no questions or support  If reviewing an interface, it’s likely participants will have problems, and it is normal to feel a temptation to help. Please don’t. Instead, try to understand why it was that the user got stuck or went down the wrong path. It’s the facilitator’s role to get users back on track if they get really stuck. And if the facilitator poses a question during the test, he or she is asking the users, not you—please don’t answer unless the facilitator specifically directs a question to you.  Avoid “Design Questions” - Questions that ask the user their opinions about how to design aspects of the application (such as, “Where would you like to see these navigation buttons?”) can take a lot of time to answer and produce only limited results. Instead, focus on trying to understand the problem—we’ll come up with solutions later, outside the test.  In person, be conscious of your body language  Although most studies are interesting, not every moment will be fascinating. If something is happening that isn’t of interest to you but may be to others, sit quietly without fidgeting.Take notes to stay alert.
