1 00:00:00,770 --> 00:00:04,420 We've talked a lot about making sure to use people from your target audience 2 00:00:04,420 --> 00:00:05,850 in testing. 3 00:00:05,850 --> 00:00:10,090 Are you showing your product to the people most likely to use it? 4 00:00:10,090 --> 00:00:14,750 Let's look at whether this study is focusing its effort on the right people. 5 00:00:15,820 --> 00:00:20,240 Starting out with a mixed gender group makes sense because we have no information 6 00:00:20,240 --> 00:00:23,040 leading us to think we need to favor one gender over another. 7 00:00:24,110 --> 00:00:28,220 The next qualifier, weight, seems irrelevant, so 8 00:00:28,220 --> 00:00:29,670 let's remove that completely. 9 00:00:30,800 --> 00:00:34,250 Another basic demographic question is missing, age. 10 00:00:34,250 --> 00:00:37,900 Let's assume we know that adults are the ones buying AC units. 11 00:00:37,900 --> 00:00:41,770 That means this study should be 18 plus. 12 00:00:41,770 --> 00:00:42,618 I'll add that now. 13 00:00:45,284 --> 00:00:49,388 Beyond that we don't information about the age of AC buyers, so 14 00:00:49,388 --> 00:00:51,674 we should aim for a mixed age group. 15 00:00:54,160 --> 00:01:01,830 Homeowners and renters, hmm, any thoughts about why this is here? 16 00:01:01,830 --> 00:01:06,630 This is an example of where it's important to really know your users. 17 00:01:06,630 --> 00:01:09,270 In the case of home owners versus renters, 18 00:01:09,270 --> 00:01:11,960 it's possible that the former will be shopping for 19 00:01:11,960 --> 00:01:16,640 a pricier longer lasting unit while a renter is just getting through the summer. 20 00:01:17,660 --> 00:01:21,010 If half of the target audience tends to be home owners and 21 00:01:21,010 --> 00:01:24,620 half renters, then the recruiting criteria needs to reflect that. 22 00:01:25,700 --> 00:01:28,410 Next, I've already included a benchmark for 23 00:01:28,410 --> 00:01:32,540 how often someone should be shopping online to qualify for the study. 24 00:01:32,540 --> 00:01:36,520 After all, if they never shop online, they're not the people looking for 25 00:01:36,520 --> 00:01:38,940 an AC unit online, either. 26 00:01:38,940 --> 00:01:42,564 And finally, I'll add a few more qualifications. 27 00:01:45,352 --> 00:01:50,816 Half should have purchased an AC unit for 28 00:01:50,816 --> 00:01:55,640 themselves in the last year. 29 00:01:55,640 --> 00:01:59,950 This way, we can hear from people who have gone through the experience recently and 30 00:01:59,950 --> 00:02:02,200 those who may go through it in the future. 31 00:02:03,870 --> 00:02:07,920 Also, all should not have central 32 00:02:09,330 --> 00:02:13,630 air conditioning where they live. 33 00:02:14,690 --> 00:02:19,770 After all, if they have central AC, they won't need a standalone unit from Amazon. 34 00:02:20,870 --> 00:02:28,690 And finally, all must have an Amazon.com account. 35 00:02:28,690 --> 00:02:31,990 Since we don't want to include account creation in this study or 36 00:02:31,990 --> 00:02:36,860 discover issues specific to new users, the easy way to eliminate that from 37 00:02:36,860 --> 00:02:41,210 coming up is not to include those without an existing Amazon.com account. 38 00:02:42,630 --> 00:02:46,740 All right, let's breeze through the last few details of the study. 39 00:02:46,740 --> 00:02:50,780 The product to be tested will be a live website, in this case. 40 00:02:50,780 --> 00:02:51,280 Check. 41 00:02:52,330 --> 00:02:57,100 Three hours for a study is a crazy long time. 42 00:02:57,100 --> 00:03:01,640 It would be very difficult to find people willing to give you that much time, and 43 00:03:01,640 --> 00:03:04,460 even harder to keep someone's attention for that long. 44 00:03:04,460 --> 00:03:07,940 60 to 90 minutes is an average length study. 45 00:03:08,960 --> 00:03:12,560 For the time between participants, we can keep that to 15 minutes. 46 00:03:14,160 --> 00:03:19,566 So let's change 3 hours to 60 minutes. 47 00:03:19,566 --> 00:03:21,171 What's next? 48 00:03:21,171 --> 00:03:23,716 Compensation. 49 00:03:23,716 --> 00:03:28,367 For compensation, a $100 Amazon gift card is appropriate, since it's a reasonable 50 00:03:28,367 --> 00:03:31,500 amount of money and you know it's for service that they use. 51 00:03:32,670 --> 00:03:38,297 The list of documents to prepare seems daunting, and yes, they're all necessary. 52 00:03:38,297 --> 00:03:42,077 You can find examples of the consent form, background questionnaire and 53 00:03:42,077 --> 00:03:44,547 test plan overview in the teacher's notes. 54 00:03:46,077 --> 00:03:48,347 And that's it for our test plan review.
