36 © 2001 Steve Krug “My ideal home page,” as told by…

37 My solution? Usability testing  Best thing I know of for quieting arguments  Based on watching users, not personal biases  Creates a shared experience  Aha moment: Our users are not like us  You’re too close to realize how little they know  See it through their eyes  It just works © 2001 Steve Krug

38 What is a usability test?  Watching people try to use what you create while thinking out loud  NOT a focus group  Focus groups are about opinions  Usability tests are about watching use © 2001 Steve Krug

39 I believe anyone can do it ...if they keep it simple enough © 2001 Steve Krug

40 Most sites don’t get tested  $$$  Time  Even if there was enough money, there aren’t enough professionals © 2001 Steve Krug

41 Traditional usability testing  Lab  Experienced professional  8 users, minimum  Big honkin’ report  Weeks of work, usually by an outsider  $5k - $10k  Happens rarely © 2001 Steve Krug

42 Do-it-yourself usability testing  Three users per round  Three should be plenty  You’ll be doing it again next month  You’ll find more problems than you can fix  No lab or mirrors  Set up a monitor in another room so the development team can watch  No elaborate recruiting  “Recruit loosely and grade on a curve”

43 © 2001 Steve Krug Do-it-yourself usability testing  Record with Camtasia or Morae (Techsmith.com) or CamStudio  No stats, no exit questions, no faux validity  No big report  Debrief over lunch

44 And now, a demo test  The smallest demo test in recorded history © 2001 Steve Krug

45 We need a volunteer  Qualifying criteria:  Have used a Web browser  English-speaking adult  Doesn’t work for AT&T Wireless  It’s painless!  You’ll get a big round of applause when we’re done © 2001 Steve Krug

46 RSME: The fifteen minute version  Six maxims © 2001 Steve Krug

47 A morning a month, that’s all we ask.

50 When this happens:Say this: You’re not absolutely sure you know what the user is thinking (see below). “What are you thinking?” “What are you looking at?” (for variety) “What are you doing now?” (e.g., if you think they’re being silent because they’re reading) Something happens that seems to surprise them. For instance, they click on a link and go “Oh” when the new page appears. “Is that what you expected to happen?” They’re trying to get you to give them a clue. (“Should I use the ___?”) “What would you do if you were at home?” “What would you do if I wasn't here?” The participant makes a comment, and you’re not sure what triggered it. “Was there something in particular that made you think that?” The participant suggests concern that he’s not giving you what you need. “No, this is very helpful.” “This is exactly what we need.” The participant asks you to explain how something is supposed to work. (“Do these support requests get answered right away?”) “I can’t answer that right now, because we need to know what you would do when you don’t have somebody around to answer questions for you. But if you still want to know when we’re done, I’ll be glad to answer it then.” The participant seems to have wandered away from the task. “What are you trying to do now?”

54 Recruit loosely and grade on a curve.

55 © 2001 Steve Krug Naturally, we need to test people who are just like our target audience. … people who are a lot like our users. … people who actually use our site. Representative users! Real users!

57 Make it a spectator sport.

59 Focus ruthlessly on a small number of the most important problems.

60 One problem: testing works too well  If you’ve done any testing, you know uncovers lots of problems quickly  This is part of the problem:  It takes far less resources to find problems than to fix them  You can find more in a day than you can fix in a month © 2001 Steve Krug

61 Problems you can find with just a few test participants Problems you have the resources to fix

62 © 2001 Steve Krug

63 When fixing problems, always do the least you can do™.

64 © 2001 Steve Krug Your motto should be…  What’s the smallest change we can make that we think might solve the observed problem?  Tweak, don’t redesign  Often the best solution is removing something, not adding something
