We've talked a lot about making sure
to use people from your target audience
0:00
in testing.
0:04
Are you showing your product to
the people most likely to use it?
0:05
Let's look at whether this study is
focusing its effort on the right people.
0:10
Starting out with a mixed gender group
makes sense because we have no information
0:15
leading us to think we need to
favor one gender over another.
0:20
The next qualifier, weight,
seems irrelevant, so
0:24
let's remove that completely.
0:28
Another basic demographic
question is missing, age.
0:30
Let's assume we know that adults
are the ones buying AC units.
0:34
That means this study should be 18 plus.
0:37
I'll add that now.
0:41
Beyond that we don't have information
about the age of AC buyers, so
0:45
we should aim for a mixed age group.
0:49
Homeowners and renters, hmm,
any thoughts about why this is here?
0:54
This is an example of where it's
important to really know your users.
1:01
In the case of home owners versus renters,
1:06
it's possible that the former
will be shopping for
1:09
a pricier longer lasting unit while a
renter is just getting through the summer.
1:11
If half of the target audience
tends to be home owners and
1:17
half renters, then the recruiting
criteria needs to reflect that.
1:21
Next, I've already
included a benchmark for
1:25
how often someone should be shopping
online to qualify for the study.
1:28
After all, if they never shop online,
they're not the people looking for
1:32
an AC unit online, either.
1:36
And finally,
I'll add a few more qualifications.
1:38
Half should have purchased an AC unit for
1:45
themselves in the last year.
1:50
This way, we can hear from people who have
gone through the experience recently and
1:55
those who may go through it in the future.
1:59
Also, all should not have central
2:03
air conditioning where they live.
2:09
After all, if they have central AC, they
won't need a standalone unit from Amazon.
2:14
And finally,
all must have an Amazon.com account.
2:20
Since we don't want to include
account creation in this study or
2:28
discover issues specific to new users,
the easy way to eliminate that from
2:31
coming up is not to include those
without an existing Amazon.com account.
2:36
All right, let's breeze through
the last few details of the study.
2:42
The product to be tested will
be a live website, in this case.
2:46
Check.
2:50
Three hours for
a study is a crazy long time.
2:52
It would be very difficult to find people
willing to give you that much time, and
2:57
even harder to keep someone's
attention for that long.
3:01
60 to 90 minutes is
an average length study.
3:04
For the time between participants,
we can keep that to 15 minutes.
3:08
So let's change 3 hours to 60 minutes.
3:14
What's next?
3:19
Compensation.
3:21
For compensation, a $100 Amazon gift card
is appropriate, since it's a reasonable
3:23
amount of money and you know it's for
service that they use.
3:28
The list of documents to prepare seems
daunting, and yes, they're all necessary.
3:32
You can find examples of the consent form,
background questionnaire and
3:38
test plan overview in the teacher's notes.
3:42
And that's it for our test plan review.
