The slides from my General Assembly workshop on January 13th, 2013 (https://generalassemb.ly/education/introduction-to-usability-testing-the-diy-approach)

ABOUT THIS WORKSHOP

Usability testing can quickly uncover areas of an interface that frustrate users and hurt business goals but many teams put it off due to budget, time, or training concerns.

This workshops will take you through a do-it-yourself approach to usability testing. We'll cover the basics (benefits, recruiting, and how to plan a test), learn how to facilitate a test to get reliable results, and how to use the testing results to move usability improvements forward. You'll walk away with the tools to hold a complete usability testing right away.

TAKEAWAYS

Learn why and when to hold usability testing
Learn practical tools and methods to overcome time, budget or training concerns that block user testing from happening
Shift the conversation from opinions and hunches to proven usability problems that your team can solve together

  49. 49. EXERCISE 1: CHOOSE A PRODUCT TO TEST TIME KEY OBJECTIVE(S) STEPS Choose an app or website to focus on today 10 mins 1. As a group, choose a website or app you will usability test 2. It can be your app/website but I must be able to interact with it 3. Avoid sites that require logging in (unless you have a login to share) DELIVERABLE A group decision about an app/website !49
  50. 50. PREPARING A TEST PLAN Test plan ! ‣ Tasks: What are we testing? Why? ‣ Success Paths: What do we expect to happen? ‣ Scenarios: How can we find out if our expectation is true? !50
  51. 51. // TEST PLAN FOR: // GROUP: // GENERAL SCENARIO ! TASK TASK // SCENARIO ! // SUCCESS PATH ! ! ! // INFO (passwords, etc) // SUCCESS PATH ! ! @ Template by @futureworkshops // SCENARIO // INFO (passwords, etc) // PART:
  52. 52. // TEST PLAN FOR: // GROUP: // GENERAL SCENARIO // PART: ! Set up the motivation What we are testing TASK TASK // SCENARIO // SCENARIO Motivation to do the ! task + instructions // INFO (passwords, etc) ! ! // INFO (passwords, etc) ! Information necessary for the task // SUCCESS PATH ! What we want/expect the user to do // SUCCESS PATH !
  53. 53. // TEST PLAN FOR: // GROUP: // GENERAL SCENARIO // PART: ! You need to cook a new recipe for the company potluck. You found a recipe online and now you need to buy the ingredients and cook it. TASK Text note TASK // SCENARIO Share a note via e-mail // SCENARIO You need to remember what to buy.

  55. 55. PREPARING A TEST PLAN !55 Scenario Tips ‣ Avoid using terminology from the interface (e.g., search, tag, filter) ‣ Scenarios can have steps (e.g., find a recipe and add it to your collection) ‣ Escalate the difficulty as the test progresses Tip: make the scenario specific enough so someone can relate to it, but not specific enough to exclude people
  56. 56. EXERCISE 2: CREATE A TEST PLAN TIME 20 mins KEY OBJECTIVE(S) STEPS Learn to write a non-biased test that covers the features you need tested 1. Using the Test Plan Worksheet, define 3 key tasks that must be intuitive and easy to use in the application 2. Identify the success paths for each task (what we expect users to do) 3. Write specific tasks, then a general scenario 4. Run through the complete test once DELIVERABLE Filled out test plan worksheet, ready to be used in a test with a participant !56

  59. 59. !59 RUNNING A USABILITY TEST As a facilitator, your jobs are: ‣ “Tour guide” ‣ “Therapist” ‣ Burst the thought bubbles From: Rocket Surgery Made Easy by Steve Krug http://books.google.co.uk/books?id=9Q3OQVyX_-QC
  60. 60. RUNNING A USABILITY TEST Facilitating ‣ Practice staying quiet ‣ Remind the participant to speak out loud ‣ Don’t give anything away ‣ Be reassuring, say thank you ‣ If they get stuck, wait (a little) !60
  61. 61. RUNNING A USABILITY TEST Facilitator Cheat-Sheet If they forget to think aloud ‣ "What are you thinking right now?" ‣ "What are you finding confusing on this screen?" ‣ "I know it's an unusual thing to do but could I please ask you to keep thinking out loud and talk as you go along? It really helps me understand your experience better." !61
  62. 62. RUNNING A USABILITY TEST Facilitator Cheat-Sheet If they get upset ‣ "This is very helpful for us, we are uncovering a lot of problems in the design that will help us make the app better.” ‣ You’re struggling with the same areas that other participants found confusing - you’re totally normal !62
  63. 63. RUNNING A USABILITY TEST Facilitator Cheat-Sheet If they have a question ‣ "Please continue in the way that makes sense to you. We will learn a lot from seeing how you proceed with this without any help." !63
  64. 64. RUNNING A USABILITY TEST Facilitator Cheat-Sheet The golden go-to ‣ "We expected to uncover problems in the design. You are not doing anything wrong - we knew there would be issues and you are helping us find them." !64
  65. 65. RUNNING A USABILITY TEST PEOPLE WILL FEEL STUPID. MAKE THEM FEEL AT EASE. !65
  66. 66. RUNNING A USABILITY TEST Facilitator checklist Introduce yourself and anyone else present Thank the participant for coming Explain why they’re here & what will happen “We are not testing you” Introduce thinking aloud Explain questions, breaks, and ask if they have any questions Optional: consent forms, recording, interview !66
  67. 67. RUNNING A USABILITY TEST Ways to record our findings From easy to complicated ‣ Pair up with a note-taker ‣ DIY recording equipment ‣ Professional recording equipment ‣ Live-stream to a group of stakeholders !67
  68. 68. RUNNING A USABILITY TEST NOTE-TAKING BRINGS DOWN 2 BARRIERS TO TESTING: TIME & EQUIPMENT (But I’ll give you some tips on recording later!) !68
  69. 69. RUNNING A USABILITY TEST Note-taking tips Only record what’s important ‣ If someone is really happy ‣ If someone is really frustrated ‣ If someone fails a task ‣ Write down short quotations !69
  70. 70. !70 RUNNING A USABILITY TEST Notes Example • ! • ! • Taps Map on merchant profile but this opens the system Maps app — confused Goes to Search and types “coffee shops” but there are no results — “why can’t I see what’s around me?” "If I had to think about something around me, I’d start the merchant profile and expect to see other things around me" ! • The icons aren’t telling me that Cafe Nero is a coffee shop ! !
  71. 71. !71 RUNNING A USABILITY TEST What to bring to the test Printed scenarios & tasks for participant Printed scenarios & tasks with success paths for facilitator Facilitator script Consent form (if needed) Pen + paper / recording tools Test setup checklist Optional: List of pre-test and debrief questions Tip: Prepare a printed copy of the scenarios & steps for the participant, they will use it
  72. 72. RUNNING A USABILITY TEST Setting up the test Reset the mobile app / site to the default settings Clear the test area of any open documents, written notes, etc. Prepare participant forms: scenarios, intro script, consent form Optional: Verify the recording equipment Optional: Make sure the brightness on the screen is reduced !72
  73. 73. EXERCISE 3: USABILITY TEST TIME 40 mins KEY OBJECTIVE(S) STEPS 1. Gain experience facilitating 1. Every round, swap one member of your group in exchange for a member from another group 2. Collect notes containing usability problems 3. Identify weaknesses in your test plan 2. The ‘foreign’ member is the participant 3. Start running through the test you’ve planned 4. Everyone in the group should try to be a facilitator at least once DELIVERABLE A collection of notes detailing usability problems found in the product !73
  74. 74. EXERCISE 3: USABILITY TEST DISCUSSION TIME !74
  75. 75. USABILITY TESTING: THE DIY APPROACH 5 MINUTE BREAK !75
  76. 76. USABILITY TESTING: THE DIY APPROACH 0 / USABILITY TESTING: WHAT & WHY 1 / PREPARING A TEST PLAN 2 / RUNNING A USABILITY TEST 3 / TURNING DATA INTO ACTIONS !76
  77. 77. TURNING DATA INTO ACTIONS !77 USABILITY TEST STEPS Recruit Participants Prepare a test plan Test Analyse + iterate
  78. 78. TURNING DATA INTO ACTIONS What to do with all the data? ‣ Identify changes with the biggest impact & smallest effort as a team ‣ Find the “low-hanging fruit” ‣ What has impact on the bottom line? ‣ Put everything else in the ice-box !78
  79. 79. TURNING DATA INTO ACTIONS Identifying key findings High-priority: people fail, or abandon the task Medium: people succeed but are frustrated and unhappy Low: people would enjoy the app more if... !79 Tip: You can’t fix everything. Pair usability priority with business needs and product roadmap to find the fixes with the biggest impact.
  80. 80. TURNING DATA INTO ACTIONS Presenting findings - an example !80
  81. 81. TURNING DATA INTO ACTIONS !81 Presenting findings Task What we expected to happen Interface screenshot here What really happened What we can fix right now
  82. 82. EXERCISE 4: IDENTIFYING KEY FINDINGS TIME 15 mins KEY OBJECTIVE(S) STEPS 1. Consider how to prioritise usability problems 1. Individually, write down 2 high-level and 2 mediumlevel usability problems on post-its 2. Discuss and agree on priorities as a team 2. As a group, arrange your post-its from high to low priority. 3. Jot down a quick summary of key findings to present to the larger group DELIVERABLE A group decision about an app/website !82
  83. 83. EXERCISE 4: IDENTIFYING KEY FINDINGS DISCUSSION TIME !83
  84. 84. SUMMARY & CONCLUSION Summary ‣ Match your test artifact to your scope ‣ Plan realistic scenarios that don’t give away the test purpose ‣ Be encouraging and open to feedback ‣ Record only what’s needed ‣ Prioritise findings for maximum impact !84
